Withdrawn from my college

Unfortunately I’ve been withdrawn from my college in my 2nd month being there as someone freshly out of secondary school. In October I was sick for 2 days due to my migraines I even went to the gp . So I had meetings for my attendance. Sometimes in college I would chat w my friends and but still take notes since it was early days everyone was just unserious in my class. However I did quite bad on my assignment I was studying level 3 applied psychology and health and social care BTEC . I’ve never done either of the subjects during secondary school as a gsce . And because I was sick and late sometimes I didn’t understand well so I didn’t pass. I think that’s when they decided to kick me out .i have appealed had meetings with the assistant principal got medical letters from the gp and my therapist from CAMHS but there decision was final. I do have a part time job but I am feel robbed honestly no places in London are taking late enrollments in January I had tried in October . I will go to a different college or sixth form next September but for now I have nothing rlly to do I’ve lost my social life due not being in college. My parents think I am failure honestly I need any advice I don’t want to do an apprenticeship it I’ll just ruin my mental health and I can’t do a apprenticeship that aligns with what I want to do in the future . Please help !!!

Your college won't have withdrawn you because you were "sick for 2 days" in October. It's much more likely to be an accumulation of factors.
Does "I was sick and late sometimes" mean that your attendance was really quite poor? Does "I would chat w my friends" and "everyone was just unserious in my class" mean that you didn't really engage with studying there?
As for "now I have nothing rlly to do", perhaps you could study - so that when you return to college in September next year, you know an awful lot already and are in a better place to do well there?
