Another collpased lung or pneumonia??

I went to the ER 3 weeks ago the day after my Boyfriends best friends funeral. I knew something was wrong before, but I had more important obligations at the time, and I could hold off for my health. I needed to be there for my boyfirend, bc he is ALWAYS there for me and always thinks about my health nore than I do...so I needed to be there. I went to the ER the day after bc I thought I had another collapsed lung, 7 hours later, 4 breathing treatments, 1 xray and 1 cat san later...I had pneumonia! What! I havet had that since I was little! My O2 was 88% so ya know I could barly breahte! At the funeral I had to take several rests going to and from the grave sight and even had to sit in the car afterward while the boys were saying their goodby and do my Oxygen...I have never had to do that before, I thought I was going to pass out. I slept with it on all night, then the next day is when I went and found out the above. They put me on Levaquin which makes my legs hurt...but it beats not being able to breahte. I got a lecture from my boyfriend about tnot taking care of myself and I thought he was going to cry, he said he couldnt take loosins me to in a matter of words. So we made a pact...and he layed down the law....every since then, I have been trying to do my best! My boyfiend is doing better but still has his moments, im just glad I can be there for him when he needs me. I pray that nothing like that happens again to loose someone so close!!!!!! Every DAY I pray that!!
