Hey welcome Davitron, I'm really glad you managed to kick all that stuff, that's no little achievement!
It's super impressive actually, and quitting buprenorphine especially at a low dose like that should be relatively easy.
I'm actually very very impressed that you managed to quit all that stuff.
Congratulations, I mean it.
Are you on antidepressants? SSRIs specifically? I don't really condone the use of SSRIs to treat depression as they are reportedly not very effective (one study in particular found them to be slightly less effective than a placebo) and can have pretty nasty side effects, but they also do seem to work for some people, so there's that I suppose.
There's also the usual stuff that's recommended to fight depression: a good and healthy diet and physical exercise. You've probably heard this lots of times but that's because they work.
Of course this alone won't completely erase your depression, especially if it's severe, but it does help, and maybe you already do follow an exercise regimen and eat healthy.
Another thing I want to add as an activity to help with your depression is
meditation.
If you're not familiar with meditation, you may be thinking it's some kind of new-age bullshit that consist of gazing at your navel and spacing out.
Well, actual meditation has absolutely nothing to do with new-age stuff, it's an effective practice that has been used for thousands of years because it works, its effectiveness has been time and time again confirmed both by people who actually meditate and by scientific research.
Meditation will help your depression, it may even make it disappear completely (it has happened to some people) or make it a lot less severe in the long term! I want to stress that we're talking about
long term, it's not a quick fix like medication usually is and it's a serious practice that you need to do everyday for the rest of your life.
It does get some time to get it right and to ingrain as an habit, but you will be so glad that you started a few years down the line.
I mean, you will feel some benefits during the first months and maybe even in the first weeks but the serious stuff comes after years, and it's absolutely worth it.
Here is an interesting article about the benefits of meditation (most of them are backed with links to researches and studies), and a lot of them are related to depression!
Also,
here is a thread where I wrote a post about meditation and how to get started, read it if you're interested! Be aware that it's very long.
I'm certainly no meditation expert or whatever but i do have some knowledge and some experience, and I also list a few books from people that are way, way more qualified than me.
Another interesting and relatively new treatment for depression is Ketamine Therapy.
It seems to work pretty well and it looks promising, and unlike SSRIs that usually take weeks to take effect if ever, ketamine provides instant relief.
Note that the doses used are very small, so it doesn't make you high.
Here is a good article about therapeutic use of ketamine to treat depression.
In my opinion though the best "treatment" of these is meditation (possibly coupled with yoga and of course healthy diet and exercise) because while drugs temporarily hide the depression, meditation goes a lot deeper and can eradicate depression and anxiety layer after layer.
It takes time and effort, but is an invaluable tool not only for depressed and anxious people but for, well, everyone.
Hope this helped and have a fantastic day/evening/night!!
which makes things harder,anyway any advice would be greatly appreciated,thankyou
