New Diagnosis and Hitting Rock Bottom

This year has just sucked!  there's been something happen every damn month.  Recently diagnosed with RA, can't find a medication to help so far.  My biggest complaint is the muscle stiffness and pain and swelling.  Prednisone is the only thing that has helped so far and I can't stay on it all the time.  I'm not trying to be a whine ass, basically I just need to vent.  In January, my uncle passed away, in February, my best friend moved away several states away.  In march we realized we needed a new roof, in april my husband was off work because of gallbladder attacks, in May he had gallbladder surgery and that's when the RA started attacking my knees and legs, then we found out our home owners insurance is dropping us because we had to make a claim for wind damage to our roof and to top it all off on June 9th we had to put our Furbaby, Sniffles, to sleep because we found out he had bone cancer.  Sniffles was and still is the love and light of our lives.  We miss him terribly, we lost OUR CHILD. We have no human children.
 
Now I am learning the RA is relentless in letting up...I'm still working full-time but we are so financially strained and all I do is pray and keep telling myself it could be worse.  I'm terrified that more bad things are to come and I don't even want to think about it.  Everytime something else goes wrong, I can't help but think, SERIOUSLY?! REALLY?! WHY God, we can't seem to catch a little bit of a break?  My God is a loving and caring God, but then my head keeps going and going and that awful thought pops into my head saying Why is God picking on us so much?  I know the God of my understanding isn't like that, but I can't get rid of these thoughts. 
 
I have hit rock bottom and I don't know if I have the strength and/or will power to pull myself up out of this awful pit I'm living in.
