Struggling to move/walk.

I'm 30 weeks pregnant and this pregnancy is unbearable at times. I can't get out of bed for ages because of the pressure. I can't drive no more because my belly is so big and it hurts when I change gears. It's becoming impossible, I can't sit down for longer then two minutes without major discomfort or pains. I also have spd. Guys how am I going to go another 10 weeks:(. I can't do anything literally the pain or aches are too strong! Will this get better?
