Is this low self-esteem and how to overcome it?

[Feellikeafool1]

I was upset because a friend didn't reply to a call and then another acquaintance a text. I go through things in my head that I might have done to upset them. Whereas a family member said to me they'd think totally differently, "it's their loss if they don't want to be in touch with me"! I'd love to be like that and would appreciate any advice to become like that.

It says more about them than you. I doubt you offended them. Maybe they got busy, maybe they didn't. Try and validate yourself instead if seeking it from others. Look in the mirror and say outloud 3 things you like about yourself and do this every day. Don't give your time to people who don't give you the same energy. If they got busy they will respond eventually.
