Hey again 
It's nice to know I'm not the only one..
As for friends, I also do go overboard with pleasing people I like.. I just tend to want less and less close friendships as I get older. Maybe it's an age thing, rather than anything else? I do however, quite happily, talk about myself to my friend
I don't get on with females that often, my best friend is a man. But I am a tomboy, so that may be why.
My boyfriend is also very lovely (most of the time), very attentive, affectionate, will sit and listen to me and try to help me all evening if I needed it. I also have to "force" myself to be positive
, this is definately something I get from my mum, and I think it causes people to feel insecure around me. My partners however thinks I'm amazing and wonderful and always praises me, but I find this hard to accept sometimes and feel crowded and claustrophobic.
I have a sister, she lives in Australia now, she's the total opposite to me and isn't like this at all. She is a party animal, very social, very much a positive energy and will always see the good in people/things first. Like I say, total oppsite
lol. The big difference is when my parents split up when I was 12, I stayed with mum and she stayed with dad. She has more of my dads looks and personality and I'm like a clone of my mum, so I guess I've inherited her emotional side too.
I just listen to mum and think 'is that what people hear when I talk?', and I get all embarrased and then I just think I don't want to be like this!! I want to be happy and not negative and critical about everything.
Funnily enough, everybody else seems to think I'm great, I'm the brainy one in my Uni class, run a sucessfull business, and if you saw my FaceBook profile you would think I was a totally different person to how I actually feel 
Have you thought about counselling? I've been considering it recently, just to talk about emotions, negative feelings and my childhood..
Do you have much contact with your mum? and do you have siblings?
