I identify with what you are experiencing. I have multiple problems, non life threatening per se, but multiple that are not conducive to quality of life. I get over one thing (or improve in it or at least get it properly diagnosed), and then another thing comes along----I fall and break ribs or an arm, then I get auto-immune problems from the steroids I took for back pain, etc. And then I get D2 from taking the steroids. (I had thought the spinal injections of steroids were the magic bullet for my sciatic/hip/back pain, and that they would allow me to travel without the max of pain meds.) Knee surgery, back surgery, etc., etc. Pulled shoulder muscles. And add to that my manic-depression, which is a forever thing. I have lost some vision and have moderate hearing loss. I try to deal with these with hearing aids and eye surgery and meds, but sometimes I feel that it is pointless. I have become my grandmother, except really less active than she was, even at ten years older than I am now. I cannot be trusted to walk across the room without falling down.
And constant pain of one sort or another, which my depression only enhances. When my family asks how I am feeling, I really don't know what to say. Should I tell the truth, or lie? Lying comes in handy because I don't think anyone would believe how bad It is, or really care except on a superficial level. I don't blame them, as I remember what it was like to be young and healthy and have no concept of the chronic pains of age.
I know that exercise would be helpful, and I am trying. Leaning over to get on the yoga mat a couple of weeks ago, I tumbled, broke two ribs and strained my shoulder and arm. Trip to doctor, pain meds, more chronic pain added to the list. So right now can't even swim slow laps, which have been a pleasant and helpful activity, especially followed by dry sauna and then hot tub.
My husband is beginning to hate me, although he tries to be supportive. I'm not an equal partner any more. I began planning a trip to Italy and booked a lovely hotel in Rome. Then last night I cancelled. Typical manic depressive behavior.
So Justnick and Lightsout, I understand your quandary. I just wish I had some wisdom to impart. Those before us just kept on trying, and I guess that is also our path. My best wishes to you. (God and I are not on speaking terms now, or I would send prayers also.)
