Dropping out of college because its making me miserable and depressed?

i started a media course in septemer. its a 9 month course and when i signed up for it and started i was genuinly excited about it and i couldnt wait o start something new after leaving school. but as the months ped i started to loose so much interest. it really wasnt what i expected it to be and now going into the course is making me miserable and depressed. its knocked my self esteem and the people in my course are less than friendly and quite y about everything. the work load has become to much to handle and i've had several panic attacks about it, and even the thought of going in. i missed like 4 weeks of the course because of this and from being sick and seriously not having money to travel to the course. i've been asked by my tutor before christmas would i consider dropping out and after christmas break i missed the first week back because of being sick. and my tutor has again said it to me about dropping and told me that the people in the college over attendance are discussing my expoltion (kicking me out). my tutor also said to keep coming into the course as normal though until i recieve a letter from the people over attendance in the college. i would totally drop out, but its my parents. they are dead set on me staying in it and making an effort. but i physically and mentally cant, i'm drained and worn out with it. i've told my parents several times how miserable its making me and about the panic attacks, one of which my dad witnessed. it feels like they'd rather see me miserable and anytime i try to talk to them about it they're like ''sure whats there to talk about, you're staying in it and thats that.''. it feels like there's no consideration for my mental well-being with them when i try to discuss dropping out. i just need them to understand in the best possible way (without an arguement) that i need to this for myself and do whats right for me. but they really dont see it that way. i feel like it's so unfair, because my brother dropped out of secondary school when he was 16 and they let him do that. ****, i FINISHED school AND i'm attempting college, but again, it doesnt seem to matter. i feel i'm wasting precious money i dont have on travelling up and down to a course i hate and am failing in because i'm not bothered about it, i'm wastin my time, my parents and tutor's time too. so, i need some advice from you guys! how can i help my parents see how miserable i am? and get them to see my point of view. i seriously need help with this one! advice and help will mucho appriciated. cheers!
