Nikki,
Brokenfriend has already posted what I was going to post today....
Your father loved you for sure. Thing is, that in my case for example, the times I have tried to commit suicide, I have been out of my mind... completely... let's say, I know my mom loves me, and I love her BUT, in those dark moments, my mind "order me" to think nobody, not even my mom cares about me... and my mind and heart feels like... "blind", or, "blank" and I cant even think that me too, loves her as well...
In those moments, we are not thinking properly....
