Feeling depressed?

Im SO excited to be pregnant after losing one in August last year but I'm not feeling like myself lately..

I don't have terrible morning sickness but it's enough that i have to eat ALL THE TIME or i feel so sick. So I've already gained about 7 lbs. (Im only 10 weeks 3 days). I'm also SO tired all the time, im on progesterone pills so i know thats definitely not helping the fatigue but its so difficult to take care of my 2 year old while im this exhausted. I also dont have a lot of family where I'm at and I literally have ONE friend. I have my wonderful fiance and my perfect 2 year old son but I'm still feeling so lonely.

I dont know what my problem is, I'm just so sad. 😪😓 And then i feel guilty for being sad because I'm so lucky to have everything that I do. I guess I just needed to vent, is anyone else just sad for pretty much no reason? 😞
