33 and a few days.....I don't know how much more I can take :-(

I haven't slept properly for weeks, spd had flared up, I can't walk without a stick and I am totally housebound. I am struggling with the smallest tasks, I can't even bath without my husband being around to help. Everything I do is exhausting and all I do is cry. I am getting around 3 hours a night sleep due to the pain. To top off what Is turning out to be a crappy few weeks my car has broken down so the one bit of freedom I did have I now don't have. I am so lonely, the pain is unbearable and the guilt of crying all the time in front of my kids and keeping my husband up all night when he has to work 6 days a week is overwhelming. I literally don't know what to do I'm feeling defeated :-(
