I would actually see benzodiazepine use, in this scenario, from what I know of your struggles in mental health indicated by this post, to be a decent option, for a few reasons. One reason is that you have been on and off Valium for a couple of years you said, which, unless it was involuntary to come off, suggests you are not too predisposed to being sucked into a full-fledged benzo addiction, but always be careful of that in any event. Another thing - you seem to know it will be the next few months that will be hardest, and require a bit more therapy via medication. So, a few months on a benzo can be fairly manageable, IF you do not become addicted (you will become dependent, it just works that way), and IF you discontinue the benzos very cautiously with a long taper, probably using Valium, so that you will not suffer wd symptoms, nor will you be forced back into life without benzos so quickly after a few months on them which could lead to issues. A short period of modest-dose benzo use could be quite helpful for you - you seem to know what works and what does not in what you have tried so far. If Valium has worked in the past, I'd go with Valium again - it is a good benzo, classic in all ways, and when dosed around-the-clock will lead to a steady level of Valium in your blood, and a steady exertion of its effect (no peaks and valleys). Another benzo that I think CAN be very good for some, depending on symptoms and other variables I am still unsure of, is Klonopin (clonazepam). It is very potent, and a very good anti-panic benzo. It has a pretty long half-life, itself, and the duration of action is quite long, too. Again, if you take it around-the-clock, you can get to a steady level of effect. I should also mention that very much like Valium are benzos like Librium (chlordiazepoxide) and Tranxene (clorazepate), and would serve, potentially very well at equipotent doses to Valium if Valium has helped in the past.
One anti-depressant class I think could be beneficial for you, based on this anxiety and insomnia along side it, is the class of TCA's (tricyclic anti-depressants). I would suggest starting at a low dose, for they are fairly dangerous compared to some other anti-depressants, and have more side-effects, but can be effective at low doses for a lot of symptoms. I'd go with a more sedating one like Elavil (amitriptyline) or even Sinequan (doxepin), which is VERY sedating. The thing I see that could benefit you with these is the fact that they are sedating, and the sedating effect wears off after usually a few months or so of use, so you would still be able to get that benefit. Also, they tend to have a bit of a quicker onset in therapeutic action than SSRI's like Prozac, Zoloft, Paxil, Luvox, Lexapro, or Celexa. TCA's act on a number of different chemicals within the brain, and produce a different sort of effect than an SSRI - they have some anti-psychotic properties, and anticholinergic properties, and anti-histaminergic properties, as well as effects on serotonin and norepinephrine. More dangerous? Yes. More side-effects? Yes. Think they might be better than an SSRI for you? Yes. Just something to consider, and if you do start on one, insist on starting on a LOW dose.
Desyrel (trazodone) could also, possibly, help you. It is an SRA, releasing serotonin and not really working on preventing its reuptake, making it unlike the SSRI's in mechanism of action. It is fairly sedating, too, and is often used in those with anxiety disorders and sleep disorders. It is another possibility, I can think of now.
Remeron might be worth another shot, though - at a lower dose or a higher dose, depending on what dose you were on before and how it affected you.
A LOW dose of Ultram (tramadol) might be of benefit to use as an anti-depressant, if you respond to it well, and haven't got a history of any seizures. It is, however, notorious for creating bad dependence, and is addictive due to the opioid action, primarily due to the metabolite, o-desmethyltramadol. It works on serotonin and norepinephrine, too, so it has some classical anti-depressant benefits with the opioid-effect boost. I don't see a doctor scripting you this for depression or anxiety, but I am just saying it could help. It is, however, known to create nasty dependence with a nasty set of wd's. And, it is addictive. I don't know if it would be the smartest idea to even go there, but I am just sort of throwing out ideas, here. Do keep the dose very low, though, as low as possible, and if you like, more frequent re-dosing of a lower dose could be of potentially more benefit. It is a dangerous drug, too, with the risk of seizures increased (lowers the seizure threshold), and is addictive, and has nasty wd's. But, initially it can serve as a good anti-depressant.
Just be careful, and make sure you don't have any health conditions that would not allow you to take a certain drug safely, and make sure you are not combining different anti-depressants - potentially very dangerous. I'd suggest psychotherapy, too, whatever the drug outcome may be, for if it will be a hard couple of months, you may need a bit of impartial support along the way. Even self-therapeutic techniques like expressing oneself through art or hobbies or whatever is great. Learn basic stress management skills - practice relaxation and meditation, and such. This can very well help those suffering these types of ails.
I guess I should be SEARCHING for people that arent brainwashed ha![:\](https://bluelight.org/xf/BL_Images/Orig_Emoji/wrygrin.gif "wry grin :\")
