Vocal therapy, or what?

Hi there. NOT a classical singer but the algorithm sent me here.

I've lost my ability to carry a tune, and I'm not sure where to go for help.

Basically, my voice has gotten shredded from years of acid reflux and/or allergies. My speaking voice is raspy and faint, and I have very little control when I sing. This is a big loss as I used to sing pretty well and loved it.

Have tried to address both reflux and post nasal drip, with no success.

Who do I see? Vocal coach? Voice therapist? Anyone ever have a similar experience?
