Dudes much as I am loath to fuel this thread any further, I must say I am more with Proactivity on this one, there are times when telling someone to man up and get on with it is the right approach (almost all times), but there are also exceptions, and these can relate to emotional issues.
A problem I can see, and I'm guilty of this as much as anyone, is to do with the male communication style, i.e. exchange of information... what we're doing is inundating Altair with information on how to be a bad-ass PUA, but the issue is more of an emotional one, and dealing with emotional issues requires a more female communication style, that is relating on an emotional level and building trust. This is something we all need to improve in our game.
So Altair I have an idea for you, will you listen with an open mind?
Before I proceed I want to explain I've been through some pretty bad shit in the last few years surrounding my divorce and the destruction of my family, accused of all sorts of terrible things, not allowed to see my kids for many months, supervised access to my kids for many months, emotionally and financially bankrupted, so unbelievably depressing and humiliating, all of this on the basis of nothing but my cluster B ex-wife's unsubstantiated allegations, well I was experiencing low mood and difficulty concentrating on my work (unbelievably enough) and so I went to seek help from a psychologist and this was really useful. Around here you can get 10 free sessions per year with a referral from a GP (General Practitioner -- means an ordinary doctor). She was very good at relating to the issues I was experiencing, and she taught me a lot about how the brain regulates emotion and so on.
Why don't you do the same. It would be very helpful for you to get some of these emotions out, your feelings of inadequacy and rejection, your feelings of being broken by past events, dare I say it your feelings of love/hate towards white girls, etc, and discuss them in an honest non-judgemental way. Now I must say that just talking about the problem doesn't solve it, it's not a magic bullet, but it sure helps. In my case I found that the issues gradually subsided and I felt this was a combination of the external improvements (worked its way through the Courts system, got my access to kids back etc) but also the improvements to my attitude, I went through another bad patch recently, but due to the tools I had learned from my psychologist I could self regulate. Now obviously a psychologist is not going to improve your game and I'd be wary of being too direct in talking about your PUA ambitions, but you can always couch it in terms like you would like to find a nice girlfriend and so on (I bet 90% of the people who go to a psychologist have this as an underlying issue).
I also, when I was having family and drug issues about 10 years back, went to a psychiatrist and this was reasonably helpful too, only a psychiatrist will want to give you drugs and I have found anti-depressants to be not helpful. Probably I wouldn't recommend them in your case. But you could keep an open mind.
Another thing I've found very helpful is simply to research the issues you are experiencing. Do some web searches, search in the library... I was looking up bullying when I came upon a load of information about cluster-B stuff and have now become a bit of an expert on the subject, but that's not all, there were huge amounts of other related areas which I collected information on, which has been very helpful in dealing with my problems.
For you I'd recommend to have a read of Malcolm Gladwell... he is mixed race, and in addition to his work being totally fascinating, he has an interesting story about his grandmother growing up on one of the sugar producing islands which had a very strict hierarchy, if you were black you were the lowest and there were different levels for octoroons, quadroons and so on... now with his usual penetrating analysis, what he points out is that, although his grandmother was near the bottom of the hierarchy she was not at the bottom and overall the hierarchy worked well and truly in her favour, this makes me think of your situation, or at least how you're perceiving it (these days we don't really think about a hierarchy but it may still exist, I couldn't say).
cheers, Ray
