My friend was diagnosed with BPD/depression last year and around Christmas time she told me that she was contemplating suicide and had been more depressed than ever. After that she largely stopped wanting to leave the house, and she hasn't worked or been in school in years. I was always there for her and tried to be someone she could always talk to, but she became very closed off and difficult to get ahold of after that. Before Christmas we would talk almost every day, but after she started taking weeks or months to respond to a text message, even if she was the one who initiated the conversation. I triple texted her a few months ago with no response, so I don't know if I should reach out again? Like are we still friends and she's just going through a lot? Or has the friendship run its course and I should give up on it?
