Nigga, you said you were 6'1 and now 5'8?
Ok. I'll try to help you to feel better.
My beloved father is 5'2 but he's muscular, since his early 20's. He had many women. Married 3 and now he's with another one. During his teen years, he was chubby. He lost the fat and got a cadaan girl (lmao) and then he married later my mother.
He was always handsome, took care of his skin and physique and with a great confidence and he had a job (still has it). So women liked him. Even though he's really short.
It's your personality that you need to change FIRST. Then slowly try to change your daily habbits. Your thoughts and then you should take care of your skin; grooming for example. And workout.
Maybe you have a low T level?Not working out and eating junk food and stressing a lot are bad for you and your natural manly hormone.
Good luck sxbi, i'm in the process of changing for the better. It'll get better walal!
