muse,

I really think the interpersonal/family stuff can carry a lot of psychological weight. Your parents maybe saying the wrong thing, or not showing the support you needed can be more weight than you realize you are carrying it around. For me, this weight is often anger. I'll be really pissed at them for not supporting me but I can't process that anger - so it turns into anger toward myself or stifled anger (which leads to sadness and depression). Just relating my experience, which might help. You might want to try to process what you are feeling about coming out as bisexual by writing - or telling it to a school psychologist.
