I think you should work with your doctor on resolving this. Using alcohol as a crutch sounds like it could lead to more problems.

Are you on any meds? Is this not perhaps a side-effect of something?

Have you tried Ashwagandha? Perhaps ask your doctor about it (although it's just a supplement), it reduces cortisol. Even if it's not a cure it could help with the stress.

Have you tried exposure therapy? E.g. going to a place outside, wait there for at least 40 mins, and see slowly go further and further. Has a doctor said anything about this?
