Thank you so much for you comment. It is tough at times.
I'm sorry you're going through this!
It does sound like anxiety, but I am not a medical professional. All I can tell you is that anxiety will kill your appetite, and makes you feel nervous/anxious, etc.
Your body recognizes anxiety as the "work" chemical (fight or flight). Sadly for us, it feeds on itself. If the body doesn't do anything with the chemical (fight it or run away), it thinks it needs more of the chemical to make the body do something. So it dumps in more. Ick!
Also, the body only produces hunger when the body isn't "working" - and since anxiety tells the body it's "working", it dulls the hunger response.
Have you talked to a doctor about all this? I would definitely focus on the good news that your HIV tests came back negative. Self-talk is huge in combating anxiety. When you're tempted to worry, just start telling yourself "I do not have HIV. My tests came back negative, so I don't have HIV."
Rather than jump back into your hardcore workouts, try something more gentle: swimming, walking, yoga. When the anxiety is gnawing on you, do some slow, deep breathing. Find other ways to distract yourself.
I would definitely speak to a med. pro about your anxiety symptoms. A lot of people have found success managing anxiety with therapy, a med. to take as needed, or a daily med.
Hang in there!
