Push everyone away

I don't know what is wrong with me. I end up pushing away everyone I'm closest to. My boyfriend, past best friends, even my family. I love them all but I can feel myself pull away when even the SLIGHTEST thing upsets me. I don't know how to fix this

growing up my household wasn't a happy place and there was constant and explosive fighting from my dad. I wonder if this might have influenced the way I am able to get close to people?
