HELP!!!!!! A bad day with my hip & leg pain. Ugh! I hate hyperparathyroidism disease

I am under so much pressure today. Tomorrow is the day I have to pull myself up my the boot straps, suck it up & get my niece & our friend to the Jeff Bates concert & I'm having a really bad day. Not just the hip & back pain but just the utter consuming fatigue. I'm so weak today after being up all day yesterday at the hospital that I seriously wonder how I can do this. Prayer is my only hope. Yesterday God got me through that MRI when I doubted I could do it because of having to lay so flat on my back for 45 minutes. God was in that tube with me, calming me, keeping the pain bareable. He will have to get me through tomorrow to but I don't want to just "get through ", I want to have fun. I'm so sick & tired of being sick & weak all the time. I hate being bedridden all the time. I have a very sweet friend whose son, age 42, passed away suddenly Wednesday & his wake & funeral is this afternoon between 1:00 -3:00 p.m. & I want to go so badly to just be there for her & support her but I'm worried that the receiving line will be so long & I'm too weak to stand there  that long so I'm just jingle here trying to make a decision. My life has been one decision after the other for the last three years. I just want to get stronger & the pain to go away so I can enjoy whatever years in have left. I know I'm blessed because I could have cancer or some other uncureable disease so I am thankful for that but when you have nothing but time on your hands, you basically are bedridden most of the time you just get depressed. I do try to give it to Jesus,  most of the time but then that ole devil gets in me & I start having a pity party. Today is one of those days. I've refused to take my feeding bag with me tomorrow because it's so heavy I believe it's the reason the pain in my hips & legs is worse than the other places I have pain. So....just another day in the life I live with secondary hyperparathyroidism.
