I can truely relate to your frustration. The thing of being committed...is that it is just a short "reprieve". It allows you to get away from the stresses and strains so your mind can recover. However, without sorting the root of the problem, things will quickly spiral back down to the "normal" state of affairs.
It is true...how ever hard it is for me to admit this...what MandMS says. It is a passing feeling and...this might sound strange...if you were to commit suicide you would be very annoyed with your self when your mood lifts and you realise you didn't have to commit suicide

.
MandMs has another good point in terms of the medication...
I have been on one medication for over two years and I'm starting to realise that it is time to get it changed. The effectiveness of the medication has slowly been dwindling without me noticing it, up to a point where, now, they don't do anything any more. I am starting to realize I need to go for a re-eval as it seems the medication only worked up to 80% which means it's effectiveness dilutes by 30% each time...
I don't know if this makes sense, but it's like when I got my eyes re-tested. I only did it cus my current glasses is starting to give in with age. To my surprise, my left eye has degraded by 1 and my right eye by 1.5. I never realised it degrading. (btw, 1 might not seem like a lot but if you compare that with the maximum of 20/20, it's a drastic change).
Hang in there! And feel free to use my shoulder to cry on if you need it. I know how it feels and I know how difficult it is to get...or even accept for that matter...support.
Thinking of you!
