You do seem a little insecure and you mask it with your 'I am insane' schtick and there are people online who WILL prey on that.
Also people are like 'OMG, she's a girl who is talking to me, she's pretty, and she lives relatively close - I hope she'll sleep with me' and I don't kno whether you are aware that some guys are thinking that and playing with them OR if you are oblivious to it and just being friendly.
I would believe it to be the latter because of your insecurities, except I do believe you're quite intelligent.
