I don't know what to study. Help!

I'm currently in the process of withdrawing from my current university and hoping to reapply to university for September entry, but I have no idea what I would like to study.

I've been racking my brain as to what I should study, but I cannot come to any conclusion as to what I want to do, and to make matters even worse, I didn't get the best a levels grades either, but I passed with CCC. But there is not a great deal of choice with those grades.It was devastating as I had got AAB at AS, but because of personal circumstances, I was overjoyed with getting CCC as I was convinced that I was not even going to get into university in the first place.

I was studying Social Science, however, I didn't particularly like it and my overall university experience hasn't been great. (Finance, being diagnosed with depression, not getting along with my housemates, as well as a lack social life.)

I was always convinced that I would become a social worker, but I would like to put that on hold for a bit, and study something else and then perhaps get a Masters instead and build up my experience a bit more.

I've looking into law, but I know that there is not much a chance with my grades, so it is becoming less of a possibility. I looked at history, English, sociology and other subjects, but I'm really unsure as to what would a good course option with my grades. I'm also worried about my career prospects, with my grades, I'm unable to go to a top university so I'm not sure what universities are best, and I'm just genuinely scared by the prospect of wasting my time again on a degree that I do not enjoy.

So it a massive dilemma for me, I'm really unsure of what to do :/
