Noticed not much activity here, but hoping/trying for help anyway!

I never had a problem eating until now, in fact most of my life, I overate. I went on WW and did really well, lost 40 pounds, ate healthier. Then my mental issues son got arrested for failure to appear from 3 years ago and I can't eat. Food tastes terrible and I feel like I'm about to throw up. I keep losing weight and I don't want to or need to anymore. In fact, I've started eating more sweets because I tolerate those better and it's a lot of calories. If I lose 5 more pounds, nothing at all will fit me and my pants will be falling off. The skinniest clothes I have are almost too big now. It's not that I am too skinny right now, 139 and 5-1/2 ft tall isn't too thin. But I NEED TO EAT.

I had an initial appt. with a counselor, but don't have a next one until over a week and she's out of the office until then.

Does anyone have any ideas of what could help to increase an appetite when someone is very stressed/anxious? I hate feeling so emotionally strung out all the time since his arrest, but know this isn't his first rodeo and he's gay and injured and has mental issues and won't take care of himself. I wish I knew how to disassociate from this!
