Today I received a message from a friend. We've not spoken since Xmas, there hasn't been any animosity or fall out, just life getting in the way. Around Feb/March I started to struggle with anxiety and stress from mainly work but also some family issues and then in the past three months I haven't worked and have been signed off. My mental health has taken a toll and I've hunkered down and tried to just take care of my family and myself. My friend today text me out of the blue asking why I'd blocked her on Facebook, why I'd not been in touch, she said she wanted an explanation as to what she'd done that was so wrong and after that she won't bother me anymore. I'm so upset. I deleted myself off social media many months ago to enable me to heal and I've just kept myself to myself. I dont want to cause any upset, or have the stress of having a back and forth back and forth text conversation. How do I respond though? I feel like I've lost all ability to deal with stuff like this.
