postpartum? FTM,help 😣😣😣

Kaia • " Teen Mom ". Having my baby girl in October! Can't wait 😍
I haven't actually had my baby yet, so idk if this is considered postpartum at all or maybe I'm just sad. I haven't been depressed since the very beginning of my pregnancy and I'm now 22 weeks. My grandmother past away last Sunday and since then I've been feeling anxious and homesick? The feeling when you've been away from home for so long and just want the comfort of your own bed type of homesick. But, I'm home everyday and I still feel this way. Like I'm missing something ? Is this just hormones or ?? Not to overreact just been feeling this way for about 3 weeks now and not sure. 🤧
