Go on a summer again

Hi everyone! So i'm a working student, I work to be able to study in my school. I have been working there for 3 years and I'm getting stressed out, I haven't spend my summer or going on a vacation for 3 years because I'm still working even if it's summer and working on scholl only gives you free tuition and No Allowances.. so i am on my own. Recently my evaluation on my work is getting low. I am desperatly wanted to go on a relaxation, maybe it will help me get back again to my work.Thank you everyone and Godbless all."There is reason for everything"
