Endo + Infections

It's well known amongst endosisters that we tend to get infections easily. We also tend to overlook some of them because they cause symptoms similar to endometriosis pain.
Take urinary tract/bladder infections for example. Endo causes bladder symptoms as is. I go more often than most people, but I go less often than I did before the lap. Anyways, the fact is, I had a bladder infection that I let go untreated for a few days until I started having kidney pain. I got very ill, and it's all because I thought the pain I had in my pelvis was just from endometriosis. Thankfully, the infection didn't get into my kidneys, but it got bad enough that I had kidney pain, which is the worst pain I've ever felt in my life. It also made me feel sick to my stomach. I never vomited a single time, but I felt like I was going to. It was awful. I can't even imagine what a full on kidney infection would have felt like. I haven't been able to eat anything other than cereal, applesauce, bananas and toast since Tuesday (it's Friday now). I am so tired of being sick. I missed one day at work, and worked only a half day before that. Tonight I'm returning for my entire shift to tough it out through the nausea. Since I'm taking antibiotics now I think I'll be okay. I have pelvic pain still but no more kidney pain. This is the sickest I've been in a very long time. I almost went to the hospital last night. I was actually advised by a nurse over the phone to call an ambulance and go but I stayed home and rested and just called my doctor in the morning. I'm fine. I hate going to the hospital..
It's rather daunting to recover from one ailment just to be afflicted with another. I finally recovered from anemia about two weeks ago and I was getting back into my fitness routine when the infection hit. I still don't know how I got it.. Sometimes I have pelvic inflammation that makes it difficult to completely empty my bladder, so that might have caused it. Women with endometriosis are more prone to infections usually and that doesn't help.
As for the depression, I've been taking anti-depressants for a couple weeks now and I'm feeling better. I had an anxiety attack last night though because I missed a dose. I need to make sure I take them every day. It's just been very hard facing grief every day from losing my brother in July and then dealing with endometriosis and the possibility of being infertile. I haven't had a period since that heavy breakthrough bleeding last month, so I think I have endo somewhat under control. I hope that doesn't happen again!
Anyways, I'm looking forward to returning to work tonight but I'm also a bit nervous since I'm still sick. I think I'll feel better as long as I drink in lots of fluids and don't overdo it.
