So overwhelmed 😓

Anybody ever get so overwhelmed they just want to be alone for a long , long time?? Im 16 weeks pregnant, I work full time, about to enter my senior year of college and my fiance (who's working two jobs) and i are trying to figure out how to move and manage finances and i cant even sleep i feel so stressed out. Its my fault though, ive always been the one the to put all the work on myself because im sort of a control freak and like to make sure things are done the right way.  I just wanna run and hide , and be alone . My man is so supportive and tells me not to stress but the only way i can be at peace sometimes is to just be alone and think 😔 it makes me feel so bad , but i just feel like im going to lose it any minute now . I dont know how to handle it all.  I just want to throw in the towelÂ
