Dear Illegal,
I think you must be a creative person to come up with this screen name....it sounds like a punk or alternative band. I don't think pics of painted nails are that interesting to look at, although my young daughters do. I am not sure of your age, but i am guessing fairly young.
It is hard not to look at facebook to see what you are missing, but i promise you that when you stop looking at her, you will be able to see clearly other opportunities that may work better for you.
Letting go is difficult. For me, it takes very long. My wishes for you to make other connections, and find other healthy activities. I feel that will be a good start.
Sandra
