Too much analyzing...I don't know how you sleep at night. LIsten, it's easy this life we live...all of us lie and manufacture problems that really aren't there and say we're this and that...bottom line is that EVERYBODY HAS SOMETHING THEY THINK NOBODY ELSE HAS FELT GUILT OVER. And that simple isn't true. You keep on bringing up bisexuality but concentrate on the fact that you're not. Who cares? In this day and age...nobody cares, pal. Get it set in your mind that you are not that unique to the world of guilt and I do believe you'll start to feel a calmness about what you perceive to be a "big deal". It ain't. So what you've done things with guys? Or told a lie to your gf? We all have lied or felt guilty about something along the way. I'm 51 and I've done things to people that would curl your toes. I sleep like a baby at night. Bigger picture...bigger...picture.
I do a form of holistic healing called The Emotion Code and we find and release 'trapped emotions' that have gotten trapped during traumatic events. Sometimes we don't even know what they are, but they are in there. You do not have to relive these events or talk about them in order to release them. This therapy is very gentle and non-invasive.
