Due to various circumstances (mental illness related - major depression, anorexia, anxiety, etc), I was forced to leave secondary education at the age of 15 or so. At the time, it was considered a temporary solution until I got to a state in which I could function and concentrate on my studies. However, time passed, and despite having access to therapy and a CAMHS team, I didn't get any better. A year later I agreed to go back into school a year down from where I was supposed to be, since I still had no GCSEs and it was thought that it would give me more time to settle down and relax before having to take my exams. I lasted a week before it became evident that I couldn't cope with the environment and I was taken out again. I'm now 17 - still severely depressed, still barely able to function in any productive or discernible way, and still nowhere near ready to attempt getting back into education again.
I'd just like to know what my options are when I do manage to recover enough to try. The college near me only appears to do a handful of GCSEs, none of them offering higher levels. Prior to my "breakdown", I was a good student and was always at the top of the class, so I feel like the option of aiming for an A-A* is important to me. Career wise, I feel totally lost and have absolutely no idea what I would like to study in university eventually - my depression has clouded my personality to the point where I don't even know who I am anymore or what my hobbies are, although I did used to be very passionate about science (Physics in particular), so I think that perhaps triple science would be a good idea, if at all possible.
Every time I think about all of this I get rather upset, despite my best efforts to stay calm and consider it all rationally. I feel like I've completely blown any chance of a future that I once had and that there's nothing for me to do anymore - after all, I don't even know what I'd wanted to do if I had the option. I'm just incredibly lost at the moment and I truly need some advice on what I can do. I'm so sorry that I rambled for so long!
