I figure this is anxiety related and I am diagnosed with it but I'm not sure so wondering if anyone else does.

I will randomly get hit with a feeling of the past and it's so hard to explain. It's not a visual flashback at all and I can't see anything but it's like I can feel exactly how I was feeling on a certain day and moment in the past. Even though it's not always a negative day that I feel, it makes me anxious and the best way I can describe it is kind of like getting the air knocked out of me very quickly. The feeling passes pretty quick but I find it so strange. It can be as simple as feeling how I felt on a random fall day 4 years ago or as bad as during a moment when abuse/trauma was happening. Does anyone relate? And again, it's really not like a flashback. I get those and this feeling is a bit different!
