Signs of Muscle Dysmorphia and When to Seek Help

I have been spending three hours a day at the gym lately and my flatmate mentioned that I might be overdoing it. I am constantly worried about losing muscle mass even if I just miss one meal. I have been researching signs of muscle dysmorphia and I am starting to check quite a few of the boxes.

It is tough because in the fitness community being obsessed with gains is often praised. I find myself avoiding social events because I am afraid the food will not fit my macros. I am beginning to realize that my mental health is suffering even though my body looks better than ever.

Has anyone here sought professional help for this? I am curious if a standard therapist understands the nuances of gym culture or if I should look for a specialist. I really do not want to stop lifting but I need to find some balance before I burn out completely.
