A friend of mine killed themselves not too long ago and I was just informed. We were in the same friend group for over 4 years. The last few years my mental health was really bad and I felt labeled as the mentally ill depressed one because everyone knew what was going on in my life. Apparently, this friend was also struggling and I feel guilty for his passing because if I wasn't the depressed one then maybe people would've paid more attention to my friend and just maybe he would've gotten the support he needed. is it selfish of me for feeling guilt regarding his death?
