Hello hidden, i'm new too and yours is the first topic i've read on here :)
Well first of all don't worry about how long a post is, this seems to be a place where it's ok to write as much or as little as you like so no need to apologise :)
Having to drop off your course seems to have been a big blow for you and it sounds like people haven't been very understanding about it either

but you can come back from all this and make a new start. You got so close to finishing but the attitude of your lecturers on top of the depression and psoriasis seem to have eventually worn you down, but you can be proud that you fought for so long, years even, you've shown courage there and i think thats something that can be a great help to you in mnoving on with your life. Again when you talk about having to move back in with your dad that sounds like something which you really have to work at but as you say you are trying day by day to get on with it and i think this shows your innate desire to fight and not to give in and i'm hoping that's something you can draw on see you through these hard times.
I think the doctor will be understanding about you missing the appointment and won't make a big deal about it and so it might be a good idea to book another appointment and talk to them about your problems, i'm not sure how you found being on the citalopram but it could also be a good idea to talk to the doctor about possibly starting a course of it again or you could try another similar anti-depressant if you were experiencing any bad side effects whilst you were on it.
Are you in any form of counselling? Personally i've found a combination of different approaches has been the most effective when dealing with things like depression - hitting it from all angles as it were. It isn't for everyone but if you have never tried it before it might be something to consider...also i remember one time i had missed a doctors appointment and i was really ashamed and scared to arrange another and my counsellor helped me find the courage to call up and sort an appointmnet out and stop feeling so guilty about it all. So having a wider support network can help when you find you are having difficulties with one of the ways through which you are trying to help yourself.
So perhaps these (doctors appointment and looking into some form of counselling) could be your next steps?
Oh..and if you dont like the idea of standard one-to-one counselling there are loads of other options in that area like group counselling which realy helped me through a low point and there and things like CBT as well.
Hope that helps :)
