Hi Johnny,
I hope you don't mind me replying - I'm a supporter of someone with PTSD. That said, I do have depression and anxiety and I am on medication for that. For me, this will be a life long thing - and I accept that. My depression has so far been life long, so that means life long medication and also therapy along with it.
I believe that medication can aid the therapy process - this has been the case for my husband. He is on a couple of different medications (as am I) but this helped stabilise him so that it was easier tackling the traumas that plague him. I believe that it has relaxed him a bit, made him more open to the therapy and it's benefits, more open to learning about how to handle things that stress him out, more able to communicate effectively etc. On the whole, I guess you could describe this as a bit of a snowballing process - the medication helps you feel calmer, can settle your mind down a bit so you get more decent and restful sleep, this makes you feel better etc, that makes you feel more positive about therapy and one thing leads to another..... am I making sense? :)
Asking questions about the medication your psychiatrist wants to prescribe is always wise, and they should always be happy to talk to you about it. Things that you'll want to know are things like what benefits you may be likely to experience and when, what side effects are common, how long he anticipates you may be taking the medication for (bare in mind, it can be a while, or it may be totally unknown), are there alternatives, is there a plan of action for other medications if certain ones don't agree with you and what withdrawal effects there may be if indeed you do need to stop taking one.
