I am so sorry you are having to go through all of this. This is an awful lot for one person to deal with. But you know you are not alone. We are always hear for you. I wish I could be there with you to give you a big hug.
I know that almost every time I have a procedure or surgery, I either sink into a depression or end up manic. Sometimes the anesthia or the meds they give you can do that to you. The is the bad thing about having BP. When I had that injection in my spine last year, I experienced a bad depression for about 2 weeks and fortunately, it went away as quickly as it came on.
I may have to have another cortisone injection, this time in my foot, and I talked to the doctor about this yesterday. He said it should be localized and not get into my entire system, but I'm still uneasy about it.
I understand what you are going through. You know you can email me anytime if you need to talk.
I hope you feel much better soon. You are a bright face on this board and I hate to "hear" you so down. It will get better soon! Hang in there! Big hugs.
