...are benzos certain to abolish a bad trip?
Neither benzodiazepines nor antipsychotics are perfect trip aborters. A bad trip may not be completely relieved with benzos, and antipsychotics could leave you hung over for a day or more, not to mention both routes would likely be associated with more psychological trauma than not taking psychedelics in the first place.
I did mention earlier that I am managing to battle it to some extent, when I was not able to do this when it began. It's less like my view of reality is warped. More that there is a war between rational and irrational thinking going on in my head. It seems to sway from one extreme to the other.
This is why I was considering embarking on the psychedelic experience, as it would seem that intensifying this war between rationality and irrationality and rationality prevailing in the trip could win it entirely. Though this is a giant risk to take. And I'm not sure I have the balls or the will-power.
I'm definitely going to speak to a doctor and see what can be done.
There may be a place for psychedelics in mental health treatment, but it's not in the case of paranoia, severe anxiety, or psychotic symptoms (not saying that you have any).
The most important thing for you will be to find a mental health professional that you can trust. You'll need to be completely open with him/her and recognize that his or her recommendations are in your best interest, which may be difficult if your thoughts are characteristically biased toward paranoia. If it's a psychiatrist, you'll be asked to describe your symptoms in more detail and he or she will make treatment recommendations. There are often multiple treatment options (e.g. psychotherapy, SSRI, benzodiazepine, antipsychotic, etc.), and the psychiatrist should discuss these with you, answer any questions, and find out what you are open to. A psychiatrist cannot make you do anything (or take anything) that you are not comfortable with
unless you pose an imminent threat to yourself or others (i.e. you're actively suicidal or homicidal).
I highly recommend at least giving psychotherapy a try for a few months (assuming you can find a good therapist) and see if it helps. As far as medication management, that's up to you and your doctor. I'd recommend keeping benzos to a minimum as they are physiologically addictive. SSRIs are probably the most benign group of psychiatric medications, though they also create physiological dependence, so stopping cold turkey is a bad idea. Antipsychotics typically carry a number of side effects, so they are reserved for patients dealing with psychosis*. You mention rationality vs. irrationality, but I'm not sure of exactly what you mean by this. If the difficulties are associated solely with your paranoid/anxious thoughts and you are able typically able to ascertain reasonably accurate explanations for external events when necessary that would be different than if you suffered from persistent delusions, in which one holds incorrigible beliefs that are held despite overwhelming evidence to the contrary (e.g. the US government is tracking me and wants me dead).
*Note: The word "antipsychotic" is a misnomer. There is no evidence that antipsychotics actually oppose some underlying pathology that results in psychosis. In fact, there is no common pathway to psychosis; it's much more complex than simply an excess of dopamine or dysfunction of the glutamate neurotransmitter system. Antipsychotics seem to work primarily by blunting the emotional response and distancing the patient from bothersome intrusive thoughts. This, unfortunately, is often accompanied by mild parkinsons-like symptoms (stiffness, tremor, decreased facial expression), akathisia (inner restlessness), and a small, but not insignificant risk of tardive dyskinesia (persistent movement disorder).
