how do you deal with tons of stress?


I live at home my fiancé and I live apart due to having no money for a house. (not getting an apartment) my mother is very very very controlling and won't let me do anything and picks fights all the time. I'm currently TTC and I can't deal with it. all the stress is hurting me and my chances for a baby. how do I deal? it's scary sometimes. even today she was screaming at me because my old job didn't send me my w2 and she thought I told them not to. I'm worried that when I have a baby or just get pregnant that the stress would cause me to miscarry or somthing... any tips would help!
