Hi abbidy, welcome to PC. Are you in therapy? Sounds like a full plate to deal with alone. Having multiple diagnosis' makes coping a challenge. No easy answers to big problems.
Figuring out what it takes to stabilize youself is a process.

What have you discovered that works for you in the 5 years since your dxs? Is your partner willing to go to a councelor with you? Have you checked out on line crohn's support groups? Are you eating? Sleeping? On disability?
