I used to not be a morning person. Now I am up, dressed, make up and hair by 7 even if not going anywhere because you just never know!
Get on here and vent. It will help. Don't let them occupy too much of your time and thoughts and certainly don't listen to that crap when he says it. For that matter- No more R talks at all!
