Pain, depressed, and 22 weeks

I have been in so much pain, a bit sick, and depressed. I'm 22 weeks exactly today and I cried myself to sleep last night. Every week of this pregnancy has gotten worse and worse. Started out just sick but now I'm only a bit sick and constantly experiencing varying levels of pain. I have a pretty high pain tolerance but it's getting increasingly uncomfortable. Basically my pain is in any part of my body sustaining weight. I had pain in my knees before and still but furthermore it's in my feet while I walk, butt when I'm sitting, and my legs/sides while laying down to sleep. I need to get a pregnancy pillow I know but money's tight. And often after awhile if I choose to ignore the pain just not to have to move yet again for the 80th time or whatever I will begin to get nauseous. I also have low blood pressure causing me to be dizzy and faint when I stand very long. I feel handicapped. I'm used to being more productive than I currently am capable of being. I feel useless and depressed. I feel awful for honestly hoping something would warrant an induction before 40 weeks. Like I do not wish ill for my baby I'd rather be in pain for years than have something happen to him but something like induction at 36-38 weeks would be a gift, any amount of time I don't have to feel trapped in my body would be a gift.
