This is low self esteem, yes?

[NAB09]

Just had an email from someone that made me burst into tears. Should block them really but just want to talk to them. We have been friends on and off for 20 years and it has always been up and down. How to I get strong enough to just walk away? I don't think she would care if she never heard from me again.

well if she didn't care if she heard from you again, why bother?

Delete and forget.

Because some times it is great.

not if it brings you down though. If you are feeling low, don't get involved if you feel it won't help you.
