I'm still here...barely

I have about given up hope of feeling better. I took the antibiotic therapy about a month ago, about 7 days into the new perscription of an antibiotic we hadn't tried before I began to feel a whole lot better. The pain in my lower back all but disappeared, I was able to go pee easily, and doctor thought we were on the right track, maybe kidney infection. After three different courses of antibiotics I had a yeast infection that was huge! So tried the perscription pill, seemed wrong to just take one pill to get rid of it after trying so many over the counter creams, but it did seam to work. Now I have to do it again, after yet another course of antibiotics. Opps, ahead of myself there. Well, I finally began to feel much better, and my cough had completely gone away after 7 days of the new antibiotic, on the 12th day I discovered what I thought was allergies in my 12 year old daughter, was a head cold. How did I know? Cause I could feel myself coming down with it! First chest pain, tightness, then sore throat, then wam- Full blown head cold. I was still on the antibiotics, had two days left to go. That was about two weeks ago. I fell hard into a very bad cold. Doctor gave me yet more antibiotics, trying to ward off secondary infections as my body fights the new cold virus. Now two weeks later I feel like I am drownding in mucas from lungs/sineses. And the yeast infection is back. Great, all the coughing has set off a huge pain flair up with the RSD, I can't sleep, can barely stand up and walking? two minutes tops before I must sit down. Stand for a shower? Forget it, between pain and fatigue it isn't going to happen easily. I forced myself to do so, and just about passed out. But as there is no cure for the common cold, I have to just suffer through it. God, I keep thinking I'm going to be done in from the common cold! Or the secondary infections from one, because I've had so much antibiotics that they will quit working for me. How do you fight a cold? Nothing I do seems to help at all!
Computer is dying, typical when it rains it pours, so haven't been able to get here much, only when computer is acting friendly which hasn't been often, new one ordered should be here in a few weeks.
On March 20 the start of spring break, we have tickets for a concert, and plans to go camping with the new camper, but now both I and my husband wonder if I will be able to even tolerate the concert, let alone go anywhere and camp. I'm so sick it isn't even an option to just push through it and do it anyway. All that would happen is I would pass out, get worse, and freak alot of people out at the concert. So I am just praying hard for a miricle, so that we can still go, don't know what else to do.
Hope everyone is doing much better than I am and having atleast a few minutes a day of mental sunshine!
