I have severe depression/anxiety, don't know whether to take the year out of school

So my depressions gotten worse and social anxiety since I began sixth form. I haven't been able to make friends since I was a late starter due to me being too scared to go into school, since then I've missed so many days off to the point that they had to take me off roll but I was so stressed and at the point where I was about to have a mental breakdown, my family aren't supportive and I have literally no friends. So right now I'm stuck on whether I should start a new school, or take the rest of the year off to find ways to improve myself where I won't have any school pressure. The thing is though if I do take a year off I will put my home in jeopardy since my mum can only afford rent if I'm in full time education, we've been arguing about that for a while and it's been so much stress. What can I do? Being in school, any school doesn't matter which will stress me out because I'm not fit enough to function there, my teacher even recommended to me that taking time off is the best thing, but losing my home won't help my depression and I really don't want that
