Exercise is not the best solution right now. It would probably complicate things, hence, your difficulty breathing and increased blood pressure. These two are potentially life-threatening, but let's not forget the immense stress on the joints and skeletal system. Therefore, exercise at this point is pretty damn well dangerous. The best solution is seeking medical attention and advice to the problem. What is the problem? You put your body under dangerous stress when you exercise. You are unsure as to how to placate your obesity without feeling the need to put your body under unwanted stress. You should be seeing your physician, a nutritionist, and later or pending your doctor's request, a physical therapist. I said "and" not "or".
If you want help then there it is. I don't know how much nicer I could possibly be. If I wanted to be an ass then I would ignore this thread like the rest of the board. There are things that you need to change, donna, and I am glad you are willing to change them. But you can't go around ignoring the solution to the problem because someone was sarcastic to you.
I made that statement because I wanted to make a comment about your typing. It looked like a 14 year old's. You said you were 50, hence, the differentiation. Don't make the connection that I am making fun of you or trying to make you feel bad because of your condition, as was suggested earlier. As far as I or anyone else should or is concerned, typing has to connection to your condtition. If I offened you then I apologize for my comment. However, I would have preferred you to address me if you had a problem with it, rather than address someone else as if I were inconsoleable.
Despite all this, the advise I have given to you is the safest means possible. Ask many questions. If any of the doctors seem wrong or erroneous, then seek a second opinion. Educate yourself or ask your doctors to educate you. The more you understand about your condition and the results of it, the better.
