So I've done extensive research and yes, how I feel is apparently common in anxiety. I will feel bad but forced myself to go on a walk with my mom and she told me I just had to stop focusing on how I felt and do. So I tried but as soon as I thought about how I felt, I felt bad again. But after I walked into a store, I noticed I felt physically better.
Is this a confirmation that this is anxiety? And that I only feel physically rotten is from stress? I read where stress depletes everything, so it would be common to feel bad if you are under stess/anxiety.
