Come out of toxic relationship with no friends

I recently broke up with my boyfriend of three years. During our relationship I lost most of my friends as he was pretty controlling. I ended up socialising with his friends more. But now we have split I’ve realised I don’t have any of my own friends anymore.

I feel completely isolated and alone. Has anyone been in a similar situation before? and what did you do to get yourself back out there and get your confidence back up? I feel really low at the moment😔
