Something is wrong and its getting worse

I always had trouble socially, academically and in general. Since childhood I am forgetful, get irritated easily. I apparently keep talking at times and don't know how to stop unless I'm told about it. I can't keep control of my anger sometimes. I also always had difficulty keeping my attention on anything, studies or otherwise. I always had these things. I had some difficulty memorizing and learning and forget to do things I'm told to do. I keep interrupting people, and if I need to say something to somebody, if they are talking to someone on the phone, something in me just can't wait and just speak up and I get anxious. I'm always been fidgeting since I was a kid. My mom says even as a kid i always had something in my hand and i fidgeted with them. This still happens, unknowingly. I'm very impulsive. I don't often know and remember or even understand what i did or said. But these days the irritability and apparently according to my mother, the talking thing has been getting worse.
