Welcome @mellymoo88 !!! Im sorry you're struggling
I am struggling with a lack of appetite too but I think its due to one of my new meds (Bupropion/Wellbutrin). Prior to that I had a huge appetite but again, I think that was my meds (Pregabalin/Lyrica).
Could it be anxiety related like others have mentioned? Or could it be medication? (You don't have to answer those questions, it's just to get you to think about it).
