Hasn't been a year I came to the conclusion that I have severe anxiety. I think it has become a bit easier after the acknowledgment. A sudden change in mood and I know the cause behind it. Before It would take over processing and analyzing my brain and try to identify things that might've gone wrong. Now I just say this mantra to myself "It's nothing, just your anxiety" And I seem to handle it much better. Although it sucks when it hits. It's like the sensation you get from love at first sight except it's not.
Just dealt with a sudden anxiety attack as I write this. Know this shall pass too.
