Molbrew, 5-HTP is just a Serotonin precursor, meaning it gets converted to Serotonin in your brain, thus increases your Serotonin levels naturally without actually manipulating existing Serotonin in your brain by preventing its reuptake like with Prozac, Paxil, and the rest of the anti-depressant medication.
I personally tried Effexor XR for several months with minor results that I didn't feel at the time but realized after quitting it. With 5-htp, I feel results immediately. Besides, since it doesn't need a prescription and it's cheaper, there is no harm of trying it.
You gotta remember though, those drugs aren't magic. They just dumped down the lack of Serotonin that your automatic negative thoughts create, thus preventing your thoughts from becoming even more negative and uncontrollable.
So, once you're on medication, you can cause some true changes in your mind's wiring by doing therapy, reading books, and occopying yourselves with many things that prevent you from thinking obsessive thoughts (like sports or hobbies)
As far as therapy goes, the first experience could always be unimpressive. I mean, I wasn't impressed by my first session either and wanted to quit. But, after 4 sessions, I kinda started seeing the benefit. Reading books is fine, but talking to people, real human beings who have genuine concerns, really helps too.
Anyways, do whatever your financials allow you and hopefully you'll recover one way or another. Just remember to occupy yourself with constructive things, that is one of the best free form of therapy available.
