I can't exercise

It hurts. Its hurts so much that the thought of it makes me unable to leave the house. Im not talking some sort of somatic effect, my body is physically messed up and causing pain.

I need to lose weight. Meds are not an option so please don't suggest.

I don't have the money for supplies or a membership. And yes, walking is free but it hurts so why would I want to do that?

Sorry, im pissed off and dont know what to do.
