Often the problem is comparing yourself to others. You said cool devs are people who making projects, impacting the community and making the world better. So simply do it no matter what others think of it. Your feeling that you're not as cool as other devs is only in your head. Know what you want to achieve and work on it consistently. That is, what cool devs do anyway.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
