Hi,
I think Im in the same boat as you. Ive no great traumas in my life, no abuse, neglect or deprivation - and yet Im a mess. My impulsiveness isnt spending or eating or drinking, though I wish it was, I just decide on stupid things and then do them! 6 months ago, I decided to move continents, and 3 weeks later I was gone, six months on im still here. I took a disliking to my roommate and a week later I moved out, I decided to quit my job even though Im in a foreign country with no money, and a day later Im unemployed.
Ive never been terribly happy, but like you say, I got by. Now though.. Im f***ing miserable! I think my weird moods are alienating the few friends I have left, I keep doing nonsensical things and saying hurtful comments. Theyre all starting to look at me sideways. I dont want to be like this!
Im thinking of buying a dog - thats the best solution I can come up with.
