Should I just give up on working out?

I've been trying to be more active lately and I've been going on a short jog/walk once a week for a couple weeks now. I feel like I'm experiencing extreme pain even for DOMS. I can't even get off the couch without wincing in pain or needing help. I've done stretching, taken ibuprofen and applied cold packs. NOTHING is working. I can't even do the bare minimum without being in pain. I used to work out regularly in high school so muscle soreness is something I should be used to. I know I'm starting over from square one and I've tried to take it easy. But this is a whole new level of pain. I feel like I should just give up. People have said to do less intense activities but I'm not even pushing myself that hard. I feel good after the workout but the following days are HELL. Am I broken? Should I just quit? Am I not cut out for exercise of any kind? I shouldn't be in THIS much pain from a simple jog/walk.
