How do I get over insane loneliness - its a major problem?

You guys have helped me a lot, dealing with the married woman that loves me, the major problem I have and why I fall for this is how lonely I feel. Crushing.

I am close to my parents/sister yet it seems to not matter at all, I sit in my basement and think that I have no one. I see people with friends and think how they believe those people will truly have their backs etc.

My loneliness I believe is a MAJOR reason why I am addicted to bad women for me, is ANY attention is better than no attention. Man…it is really killing me.

I try to get away from that woman, but then its like she sends me presents and my loneliness says ‘See? She does care.’ That sends me into dark thoughts of why I only get some attention, why I have no other girls in my life and so on.

It is like this void in my heart that drags me down. I see people happy around me, and it is something I can’t imagine.
