Am I overreacting?
Me F (20) and my fiancé M (21) found out a couple months ago I was pregnant and I have been having issues with my older sister (26) and her boyfriend of 7 years broke up a couple months before I found out I was pregnant but when I announced me being pregnant I felt like things have changed a lot between me and my older sister I mean our relationship was rocky before because she bi polar but it’s even worse now it’s like she envy’s that I’m engaged and pregnant there’s always some remarks how I’m young and she made a joke about how she should find a random guy to get knocked up by she wants to be in the delivery room I have said no and she got mad about it and she tried moving in with me and my fiance but once again I said no and I told her it’s because I want to start my own little family an that I don’t want her inviting people in every night to drink and stuff it’s I mean its a 3 bedroom 1 bathroom so she could move in but I know the issues that would come with it and when I tried talking to my mom about it and she got mad and said that I was being rude for not letting my sister move in and that we’re all we got and I’m going to regret it and what really got me was the other day I had several ER visits Because I couldn’t stop bleeding, I found out I have placenta previa, but when I came to visit my family, she kept making jokes about it, and I finally snapped, and I got angry, but I also added that it’s not something to joke about and that the doctors thought I was going into preterm labor (16 weeks) and that I could’ve lost my baby and that I still can go into preterm labor and I told her that if I lost my baby, I would never talk to her again. Am I overreacting?
