A therapist is your friend. Call them today. Call a help line, even if it's Thanksgiving. The way you deal with things (your BF's sister (NOT YOUR SIL) disrespecting you, your BF's family's illnesses, your attitudes towards sex/porn), is not healthy. You CAN get better, if you WANT to. But NEY is NOT the right forum for your issues. This is NOT bullying just because it is not something that you want to hear. You 'sticking around' does not 'prove' how strong/smart/cool/adverse to bullying' you are. It just shows that you are in denial and don't care what anyone here says unless they agree with you. Please seek help. Sooner rather than later, because I honestly truly worry about you and the path you are on.
