That's really tough. Be kind to yourself. For scapegoat children of narcissitic parents and highly sensitive people - we see struggling relationships (including friendships) as our responsibility. We tend to put more energy and effort into relationships and then when they end, we carry an enormous amount of guilt and shame. Be kind to yourself. I broke up with 2 of my closest friends in the last year. I'm still to write fully about it, but it was really tough.
