well, by 'everyone' do you mean friends? you are 18, and while there's nothing wrong with that, that age is a tumultuous time with big decisions, life altering choices [and yes, even hormone changes] it can be stressful even without a child. the whole thing could be a misunderstanding since both you, your friends, your boyfriend, and even your parents can live stressful lives, could be confused on their life choices, or plain tired. did your boyfriend 100% understand what fatherhood meant? he could be stressed because he can't hang with his friends, or pursue a dream, and basically has to grow up. [please note, i'm not saying you made a mistake, i have plenty of friends who had children young, they are all wonderful parents, but i understand the sacrifice and compromise needed]
when was the last time anyone [parents, boyfriend or yourself] had a break? your parents might need a relaxing retreat to recharge just as much as you or your boyfriend do. look into meditation and various relaxation techniques. you could also be looking too deeply into things. take a step back and ask yourself if you are over-generalizing, or over-analysing someone or something.
if it is something like a curse [which i doubt] look into a cleansing and protection on your family and your house.
