Feeling down

A few months ago I had a late miscarriage at 21 weeks.. it’s been hard on my boyfriend and I but we have beeen there for each other regardless the ups and downs... the due date is in a few days and I’ve been feeling sad. It’s also other things bothering me but that’s the main stressor .. anyway lately I’ve been acting like a complete b**** towards him. Like everything pisses me off or I make him feel unwanted.. I just need a little advice or tips or someone to talk to ANYTHING I have no friends 😭😂
