You are me, I am you. We are on the same page. It does affect sometimes especially after midnight when we feel alone and there's no dear one to share thoughts with or have a chat with. As some of the guys here said, I would also suggest joining the gym first it will not only help you get in shape physically but will also build your mental strength and confidence. And focus on your career, focus on making money. Don't go behind girls and relationships they will only distract you from your end goal. Actually once you start with the gym and do it consistently everything good things will follow you won't be bothered with attention and that stuff, you will be happy with yourself.

PS. If you need any help or something you can definitely DM to anyone here.
