I feel unappreciated. 

Stop waiting to feel appreciated

1. I do something.
2. Person will like me.  – give up waiting for appreciation.

What can I do?

What can I do that I find interesting. that I like. 
Just keep doing things that you like. 
Never look for approval from others. 

Become MORE of what you are, not less. Do all the things that YOU like about yourself. Whether others likes it or not. 

Do not look to be accepted.  Just be yourself completely.

Do not shrink yourself to be more comfortable.

Be willing and ready to lose some friends

Become proud of yourself. Then you won’t need as much external validation.
