That's a brilliant and honest post Alex, thank you.
SA - The others are right. You need to see your Dr. You need to tell them everything and exactly how things are for you. No point saying that you're "fine" when you clearly aren't.
I'm impressed that you sent that email. That is much more thoughtful and much more how I think of you. You can do this, you can get through this and you can be happy - but you are the only one who can make that happen.
