I've suffered from health anxiety for months. In last couple of months, I've developed constant bloating, abdominal buldges and pressure, what is it?

Check up. It's really hard to say. Are you conflicted because you don't know if it is anxiety or something else? Are you worried about getting it checked out by a physician because you are so anxious about your health? In either case do get it checked out. Tell your physician about your anxiety, it will help you to know. Best wishes.
