I took a moment to look at @geoff_t 's other posts/threads to get an idea of his perspective.
All I gotta say to him is “Please stay in your lane”. Novices giving other novices advice is dangerous, even if it does mean well.
That being said, I’m with @kd13 on this. This kid is way too small to be cutting.
Seek the aid of a trained therapist. Anxiety and phobias are disorders and require treatment. Fix your mind before your body.
Work on your upper and mid back (lots of pulling/rows).
Your chest looks sunken because everything is getting pulled in by what pects you do have. Get your back stronger and your shoulders and chest will square up.
When I was in HS people use to say Curls for the girls.
Today at the hotel gym I literally heard these college kids say “Rows for the hoes”.
How times have changed!
Maybe the “bench press your way to glory” days are fading?
I say “Rows for the does” because it’s less objectifying and has a more hunter/gatherer vibe
Kid needs to go on a cut like I need penis reduction.
