I have to agree with starfish, find someone with a sense of humor...it always seems to get me feeling a lot better. In fact last week I relapse and my co-worker was the one who snapped my out of my funk, even though she didn't even realize it. If you are a good worker, your boss will know that and kind of leave you alone...mine did :-) I'm back to normal...and you will be okay too. Just keep it up, and you are right physical W/D are the easy part...the pyschological part is really, really tough. If you need to talk feel free to PM me.
Amen to what Starfish said - - great advice -- keep on keeping on. All the best.
This too shall pass. Keep on keeing on, it does bet better. Just the fact alone that you are at work is great. Don't look back it robs you of a future. You can do this, keep posting it helps. Get around someone who will make you laugh. Get up and do something physical it helps. God Bless you and hold You in His Mighty Hands!
