I feel crazy.

I'll start by saying that before I got pregnant I struggled with SEVERE anxiety. Since I've been pregnant it's been non existent. I'm 36 weeks and today I woke up fine, until I texted my husband a news article. He said "hey beautiful" and something in me just clicked & I was convinced he accidentally sent that to me. He doesn't send sweet texts often so it seemed random & threw me off. He's an AMAZING husband. I have literally zero reason to think he's cheating on me, like at all...but it was like something just snapped inside of me and I'm feeling so anxious and depressed. I've slept most of the day, have a pit in my stomach. It's like my brain just snapped back into my old pre pregnancy anxieties. I've sat here looking at how fat I've gotten and my stretch marks and I'm telling myself "of course he's cheating on you, look at yourself" I have no reason to feel this way yet it's so strong. I hate it. Now I'm afraid I'm going to experience PPD or be completely depressed from here on out. These months without anxiety have been absolute heaven & I feel thrown back into hell...me against my brain. Adding anonymous because I post a lot & I'm embarrassed.
