About to be 11 weeks

I'm really struggling right now mentally with this pregnancy I'm so irritable and upset all the time. Like I just now took my announcement pictures and all I wanted was for them to be over because i was so annoyed. And afterwards all I wanted to do was cry. I'm so nervous and feel totally unprepared and uncomfortable. I live in my in-laws house and dont want to be once this baby is here and I share 1 bathroom with 3 others. Its getting really hard on me mentally because I'm always stressing about not being in the bathroom too long, trying to eat even though I can barely make it down the stairs without nearly passing out so I end up waiting for my husband to come home to eat. And I feel like I'm just burdening him. Sorry I just needed to get this all out. I didnt know where else to go.
