Hello lgray3911,
What a terrible time you are having, but you will find some amazing ladies here who can help, and we are all ready to give you a hand. I don't think there is anyone who hasn't had tears. I myself have felt the same as you, it does get better.
For the constipation I found I would have prunes every day, when you go for chemo they will probably tell you chemo can cause this also but they can give you something to help. Sorry I don't have any clues that may help with the strange feelings you are having, my guess would be that it is the painkillers!
Take one step at a time and take a breath and it is ok to shed some tears.
Thinking of you.
Michelle
