Does it worth to work hard in college now?

Hi,
I wanted to ask someone who studied himself as this is a bit complicted.
i am on the 2nd year in college in design related subject, its just Foundation degree and i would like to get at least BAHons the full degree. i like to study, and like to work hard, i am competetive, but this is how it went: last few years i strugled in my life i didnt know whats wrong with me, i studied diploma in fashion design but i sufered depression, anxiety, insomnia, it went worse and worse so i trough its part of my personality or that something is wrong with people, being paranoid,through they causing me stress, the course is bad etc. i droped out a month before finish.ouch. then i applied to specific course , moved to other town, i fortunately/or unfortunately got in as in london they wnted exams of english which i didnt make.-again i blamed the organisation...on this course i mnaged it somehow, visited Dr couple times with some problems, then during holidays i was relly bad, my hair fell out, it said from blood results my sugar is high. i managed it with diet so my brain was thinking a bit clearly,altrough i had hypoglicemia, depression, then eye problems, very bad insomnia, an when i came back to 2nd year ,i relised i didnt learn much in first year, or i forgot many things. my memory was really bad.
i had to learn everything now again and catch up with work during christmas as yesterday i had to handle in assignment.

The thing is, to continue on full degre i need to achieve merit overally at least,but i didnt handle in this project so it would be just pass.this project has high points.so i lost. maybe there could be possibly chance to catch it with other assignments in other subjects, we done just two.
in both i got just pass. because i didnt realy feel good. depresed, unmotivated, the insomnia and then wake up in morning and then library was just unmanageable. before christmas when i went to see dr again i got sick note where dr said i suffered depresion in past.i was laughing as i never had depression. but now i see dr was right...

10 days ago i got results from another test, and got diagnosed with hypothyroidism.so i got medicine and straight after 1st pill it was like me 4 years ago. i felt wonderfull. i even feel i lose weight, i want socialise, i have no brain fog,its fantastic.they had to realise the change in me in college i think as people an stuents behave different to me.they r more confortable with me id say.
now i have two choices. to continue with work hard in college to hope i'd over achieve in all other subjects-we have final project, esay and three or four other assignments. that would mean id spend next six months in library and college with minimum time socialising or doing other activities.
OR to just get trough with pass, go to few classes, have fun, find work placement, earn some money, then go to apply to uni study something similar but not sure if they would take me to BAHons,or go to continue study this subject in other country but that would mean id have to get a job there, and must be private school probably because i speak only english and in my country its no enough colleges with this subject, same s in Englan. only three, in one they r very strict,they want to have that english elts level 6,5 read references (which would be bad as one of teachers is sadistic preak who makes fun of me since first year)but would need to explain situation-that my health is manageable, and altrough my work is nice, its competetive there.
it might be competetive everywhere, there are only 3 colleges in uk with this subject. so they will look on academic achievement.

I am at age whene people have families, it mens i cant afford to lose year like i was 18. i want to start my family, to be honest i dont like so much england, and there are other countries (italy, spain) where they are better than this country (i mean this subject at college) but i dont know the language! and secondly at this moment i am poor, jobless and receiving student finances. if i moved abroad i have no idea how id be on financially. but the main prob. is probably the language as i think in italy even in private school there is no english.

what do u think about it? have u any suggestion?
