I suffer with depression and anxiety. I started back on sertraline 2 weeks ago for it. Since about then I've lost my appetite completely. I'm technically underweight for BMI (but small built so not massively stick thin or anything). I'm finding it harder and harder to eat. Not sure if this is a side-effect of the sertraline (it is listed as a possible side-effect), or if it's a symptom of the depression/anxiety. I just tend not to eat at all, all day, until I make myself have some junk in the evening just because I feel I have to get some calories in. I tried to eat at lunch today and just couldn't. I even went to starbucks thinking maybe I should drink some calories if I can't face food, but I looked in and I just couldn't - I can't explain it. I bought sweets and crisps and dip on the way home and ate some this evening just to try to make up some calories. I don't want to lose any more weight, I don't think I'm fat, I'm happy with my weight/size now, but I don't want to eat. Is this an actual problem, or am I overthinking because of the anxiety? Sorry, any responses gratefully received.
