5 years ago, my OCD started and a very long nightmare started with it. I developed all kinds of mental illnesses with it including depression, anxiety,, social anxiety and even agoraphobia. I tried doing CBT on my own without drugs for a year or two and I failed, I tried Psychedelics and I suffered through many trips ( LSD appearntly increases OCD and I felt my brain was like a rapid dog), I tried SSRIS with no benefit.  I felt hopeless, I couldn't get out of this bad state, no matter what I did, it is like all I learned from spirituality and personal development was total BS. Anyways, I started seeing a new psychiatrist recently and he gave me  3 drugs with high doses each. now after a couple of weeks, I feel totally different. My OCD is almost gone, anxiety is very low, my mood is becoming better and I am gaining my strength back. I feel zero side effects except for some dry mouth and low libido. Things I learned from my experinence: Psychiatrists generally may underestimate the severity of your mental illness especially if you were unable to convey this for them and they are very conservative with drugs and dosages. Don't be afraid from side effects, make sure your psychiatrist understand the severity of your case and ask him for a multidrug appraoch  Keep experimenting with different drugs if some of them don't work for you. There are a lot of combinations you can try. Don't underestimate the importance of drugs in treating mental illness. They make you escape the bad mental state so you can work on your traumas. Treating severe mental illness is almost impossible without drugs. Psychedelics are not the way for severe mental illness. If you want to do psychedelics, do microdoses not full trips. SSRIs are a total bullshit when it comes to severe mental illness and they cause fatigue and even depression, lol  SNRIs gives energy, and feel much better. Lamotrigine ( a mood stabilizer) is amazing.
