My boyfriend will never understand

I feel like my boyfriend is constantly complaining about how tired I am or if I have a headache or anything. I work a lot and go to school full time as well as make a lot of time for him, so I’m always busy. I sometimes come home from work with migraines so bad I throw up and he just uses all those time against me in fights to say how I’m faking it and stuff it’s so hurtful to hear. His life is significantly less stressful then mine so he just doesn’t understand at all. I feel so alone and the fact I’m reaching out on here for a safe place to vent just reminds me how alone I feel. We’re supposed to move in together soon but I feel like I can’t really on him in the bad times like he’s only okay with the good times. It’s all so hard I don’t know what to do because I do love him so much.
