Dealing with Chronic Pain: My Body is Killing Me

My body is killing me right now. It's not even that it hurts to the point that I need a hospital right now, cus even when I did last week they barely did anything. I've just been in so much pain for the past month and I want to feel better already. I want the pain to go away so I can walk again, just actually walk around and sit up without feeling like my legs are cramping up or like my back is locking up. Not to mention that I can't eat a lot even if it's super healthy without absolutely destroying the toilet rn cus I have Proctitis and IBS. I'm gonna scream why can't my body just be healthy? I don't even know what's wrong other than the Proctitis. I don't know why my legs and back hurt as much as they do or why I've been getting migraines everyday for the past month. I just feel so sick and low on energy. I wasn't the healthiest before but now I'm just freaking miserable. :(
