What is coming through a lot of your posts is your childhood and what you need to work through to overcome some of the burdens you carry. I think what is so amazing is that you are already on that journey as you are willing to talk about it and recognise it and sseek therapy to overcome it. I definitely think nurture has a big role to play in our happiness, but then, i was raised in a super loving and stable family and I still haven't been entirely a happy person - mostly so, but not always, and not evenly. So definitely don't rely on that for a marker. I have a friend who is super positive and happy all the time and she had an awful childhood. I guess there are no real answers, but go the Dalai Llama, he's got it going on there... :)
