Moodiness....

Lately my anxiety has been off the charts (I have a lot of things going on right now) but recently I've been getting mad at everyone for petty reasons and I get super moody and my depression has spiked (maybe because my bf is out of town) but I don't know if it's just stress or something I need to take a look at :/ also, does anyone else have stomach problems?? Been having them about a year, no matter what I eat or don't eat I get severely nauseous all the time
