Stomach bloat / chronic constipation

**THIS IS ME BLOATED ON A GOOD DAY**
I suffer from chronic constipation and bloating. I am dairy/meat free and have tried being gluten free. Nothing seems to help. Any advice or tips?
For the record, I've had constipation problems literally my whole life and have consulted my doctor numerous times with absolutely no help. I've even had to go to the emergency room several times from being so fucking constipated.
I suspect I might have IBS with constipation as the main side effect... but any advice please it can be so uncomfortable and painful
