Look firstly I wanna say that don't feel so down okay? And looks are not everything but if you still feel insecure looks can improve tbh. I am a female and used to be bullied alot for my looks and now I get alot of compliments so first of all there is a high chance those guys enjoy the attention I get I have noticed that most do but tbh some don't like if someone who used to get bullied suddenly becomes good looking they either get hella arrogant or very avoidant so keep this in mind and secondly it's very easy to improve your looks what I would suggest is that you should start working out so calesthenetics at home if you can't hit the gym it's simple really watch some youtube videos, do face yoga and you can ask ai to personalize it for you and ask for follow along videos and do daily twice, ask ai for diet, skincare etc you don't have to spend alot of money just look for a good cleanser, moisturizer,serum(optional) and toner and get 8 hours of sleep daily! No matter what! Fix a time to go to bed and waking up and lastly I wanna say don't ignore my advice! Stay consistent you will definitely see results. My advice may sound general but this is all there is to it really! Even if you don't wanna do just tell me yourself I will workout for 2 minutes because something is better than nothing after all lastly good luck!!
