What just happened to me?

Hi All - I woke up this morning and felt okay. I decided to get up and clean my kids rooms. Going through old toys and throwing things out. I was not moving at a fast pace but after about 30 minutes I started feeling tired, my vision became a little blurry and my neck and back of the head pressure began tightening up. I stopped to fix myself something to eat and I started feeling funny. My stomach started tightening up and I had to go to the bathroom for #2 suddenly. (Sorry for TMI just trying to understand what happened) After that I still was feeling very tired but tried to eat a little somthing. All of a sudden my knees started feeling very weak, my legs felt so heavy and I felt like I was going to pass out. I couldn't catch my breath. I tried to lay down in bed but that made it worse and my heart started pounding very fast. I was going to call 911 but I started taking some deep breaths and it has slowed down.

Anybody know what could have happened? I've been on antibiotics for 4 weeks and thought I was on the road to recovery but feel like I am kidding myself.  

Man.. I wish I was waiting in FL. I moved from CT to FL and lived in deltona for a little less then a year and I had to move back with family because of my Lyme. The cold is awefull on my Lyme.

My guess is a herx also. I had similar experiences when I first started Doxy. I was confined to bed for about two weeks. After that had a couple of episodes similar to what you describe when I nearly collapsed. If you are supposed to take your abx with food (like doxy) that may have triggered something. But it could be more serious so call your doctor.
