I think people here can relate easier to my dilemma. Given that I do not have social security net (friends, family or partner) and live in a foreign country with a real risk of unemployment and homelessness, shall I quit my job that makes me depressed and has no career prospects? On the one hand I can fill in my days with activities that would eventually make it easier to get a more satisfying job, on the other, the anxiety about lack of money might drive me crazy. I have savings for 12 months and I am 28 years old, physically healthy. 

During the months that I worked there, I think I aged 10 years, didn't make any new friends, my mental health deteriorated, self esteem is lower than ever, but this job was something which at least paid my bills and gave my life some structure. I do not have any special skills and am in the process of finishing uni program in the field with a very low employment rate. I am miserable with this job, but I might not survive at all without it.
