so irritable and pregnant

this pregnancy has me irritated especially with how disconnected my mom and sisters been towards this pregnancy where Im bout to give up telling them how me and baby are. maybe it hormones but I have helped my sister out for years and acts like victim whenever something happens or expects me help her money wise. I'm at the point where I need to just not talk anymore I love my folks but they give in to help her. she still owes me a lot of money but I gave up on that. it just too much drama and stress to keep track of her excuses and sorrys every time. I had tp vent since I know my mom would vet emotional again if I tell her we had many talks about this. idk for few years ohr relationship has gotten complicated with her and. my mom.. where my in-laws are more involved and I just had enough, I have cried cause of her crap she tries to pull. has anyone had to cut ties for awhile or permanently. sometimes blood can be so damn draining
