Hi J.,
You definitely have been hit with a lot, and it does always seem like the troubles of the world gang up and kick you when you are down. You got good advice from people who know people living with Lupus, and I too have a friend who was diagnosed with it 20 years ago and has since raised 5 kids, and while our lives went different directions, I still hear from family that she is doing well.
Maybe you are just venting, but it sounds like, in addition to the other things you are dealing with, you may be depressed as well. If you are on a hormonal type of birth control - the pill, depo provera, the mirena iud, etc, I would try to switch to something else. If you are not on a birth control, I would bring up your depression issues to either your gynecologist or md, and get your hormones checked out. I was post partum due to BC after my daughter was born, but I didn't really notice HOW depressed I was until she was a year old, and really, in the beginning I was fine. Once I got my hormones straightened out, the depression went away, and it's AMAZING how much better you feel. Sometimes you don't even know you were depressed until you are not anymore, and then you think WOW, I'm normal again, I've got my old self back.
I've had tough years since then, my mom got diagnosed with cancer and needed and received a bone marrow transplant, my husband went to the hospital with heart problems, and my father in law died, all within a very short period of time, and when you receive blow after blow, you do feel like why me? So, maybe you don't have depression issues, but I would look into it. Like I said, once you rid yourself of the depression, it's like a giant weight has been lifted from your shoulders, one you may not even know is there until it's been removed. And for me, the depression was all hormonal and did not require any drugs like Paxil or prozac or whatever the drug of the day is. I just switched from the BC shot to the pill, was on that for a few months, until my hormones were back to normal, and haven't been on any since. (I had stopped the shot myself for 6 months without switching to something new and that didn't help - depo seriously messed up my hormones, but that's an issue for a different post).
Best of luck with your Lyme and Lupus diagnoses. It's early, both you and the doctors will need to find out a lot more information before you really have to worry about them - as scary as it is right now!
