I was recently diagnosed with bipolar disorder and that's been making it hard to keep all my friends. Just yesterday my best friend of 6 years told me I wasn't her friend. I should have known from the beginning that she wasn't worth my time...
It has been hard to cope with lots of things and my advice to you is if you friend won't stop ignoring you or hurting you emotionally. Leave them they aren't worth anyone's time.
Amen
