Like most of us here. You can only control the things you can control. Like your fitness and physique. Your clothes, how well you dress.
Unfortunately hair loss at a young age is a severe confidence killer. Do your best to control the things you can control.
Use the only treatments available that work. Rogaine, Propecia.
Save up for a hair transplant.
Not much more advice I can give you. It f*****g sucks bro. I am 27 and my hair loss has been pretty rapid. I went from a Norwood 2 to a severely diffuse Norwood 2.5 vertex with thinning all over in a span of 3 months.
My hair looks like complete sh*t.
