Ask Pilot here for a FAA Medical Examiner (AME) in your home town.

One of the Pilots here will be able to point you to a helpful Doctor - as some AMEs are not helpful, or will quickly/inaccurately document your issue as career ending.

Have that AME to give you a FAA Class I medical certificate (or even better, screen you for those items before applying for the certificate).

you don’t need the Class I to be a student Pilot, but if you can’t get one it doesn’t make any sense to spend any money training for a job you might not be able to hold.
