Sameer, I used to have anxiety very bad:mainly, when running late to work, I'd have horrible chest pain and suspected heart trouble because my mom had open-heart surgery when she was 35 yrs. old. But, the cardiologist told me my heart was one hundred percent fine. And that I had anxiety attacks. My mother used to hit me and scream at me in the mornings when I took too long to get ready for school. So, I felt silly for having a psycho-sematic illness and nearly never have those chest pain attacks anymore...maybe two in twenty years. Also, I wrote a list of how I was late, so worked on that. I always keep my room and house as organized as possible, even labeling things and throwing away as much clutter as possible. It helps.
I also keep a journal nearly daily to 'vent' my frustrations and keep lists of my annoyances and problems and list possible solutions. It helps to organize my thoughts. I also keep a list of my greatest achievemments and 'gifts' and read them when very nervous, like before a job interview. I try to remind myself that 10 years from now I won't remember this little bit of anxiety or will laugh at it or just be shocked or confused by it. All of this helps.
I still have socialanxiety (mainly because I think so differently+ am used discrimination and problems with people), but it is much worse when I don't leave my home or try to talk to people. I read a book about it, and it said that getting over anxiety is like exercising;you must use these skills/muscles often to be 'ok'.
