D.,
I am really sorry to hear of your relationship trouble.
I know how difficult this must habe been.
You have had some significant stressors recently...so a certain amount of anxiety is both expected and normal.
...add a hangover into the mix...and it would be surprising if you did not feel less than calm today.
You'll get back on track soon. This is a temporary setback that happens occasionally.
Work your coping skills, stay in the moment...and keep posting as needed for support!
S.C.
