I have the same feeling as well.
I am 39y this. As a woman, it means my fertility window is very short. My ex just broke up with me recently. A relationship i thought would change my life but it ended, unfortunately. I was hopeful before the last 2 months but I could not save it. I was selfish, indecisive and uncommunicative that led to this state.
I was severely broken from depression, hopeful then back to the same state only worse (current). The thing is time don't wait for us. We don't get any younger. Women like me, the clock is tickling every sec. When I was younger I wouldn't give much thoughts to it but right now, I do. There is no hope for me. I lost the person in my life, someone I am attracted to so much who loved and cared me once upon a time. I lost him forever. I did smtg that made him and his family hated me vehemently. I wish I could take away their pain...
With every waking day, this guilt is getting stronger. I will never forgive myself. My sense of purpose in living is just to be alive for my family. To live another 10y is agonising. Since the beginning of covid, I could never pictured myself in the future. It is a void.. perhaps this is a tell sign...
