Please help. Im really really depressed! Thanks.?

And my stomach kills so much I have terrible bowel problems where I cant poo for days on end and it is pebbles. Even after enemas and laxatives and everything over the counter I have tried, they dont work and I still feel really really bad. I only go pee once a day and it stings like help and the flow is very weak and nothing barely. I have been to a million different specialist, different tests, and everything is negative and fine. None of them will give anything to relieve the pain. If I ever find an answer. I cant ever sleep, or barely get anything down to eat. And lay on the couch 24/7 feeling like labor cramps or getting shot all day everyday. And no dr has done anything. I have lived with this pain for awhile now and it is a living nightmare and just really cant take the pain anymore. Should I just give up on life I just dont know what to do, What could I do it just kills sitting down or doing anything all the time.
