Dropping out of school?

I'm thinking about dropping out of school.

My Dad mentioned it as a possibility tonight and I just instantly thought YES! My only downside is that I have just spent 1 and a half years doing my A levels and if I give up now then it would all be for nothing, all the anxiety, all the stress, for nothing. I don't really know how I would feel about that because right now, I want nothing more than to be done with school and all the stress that comes along with it. But then if I drop out of school will I just give up on going to uni altogether and do nothing with my life? Oh I don't know what to do with my life it's so hard to know what the right decision is when i'm confused and struggling with mental health issues, I mean it's haard to know anyway but with my anxiety and depression constantly telling me to never leave my bedroom, making rational decisions is very hard.
