I still suffer from anxiety occasionally these days, but basically I forced myself into situations I fear years ago, and as a result, I actually love speaking to people most of the time, bantering about nothing, (well, except to girls my age, I have a few girl friends but new women, I'm generally very anxious, I think a lot of guys are though
). I work in IT too and pretty much everyone says I'm probably the most social guy in the office and how I apparently make people happy when I come in because I ( apparently, I feel like a zombie and wanna go back to bed usually haha) always look happy and smile and greet people.
Howver, I regularly suffer from anxiety attacks in bed, usually before ''anything'' new I have to do (next day) but also completely at random sometimes, I just feel stressed, I'm concious that I'm anxious but can't calm myself. I've resorted to sleeping pills in these situations as usually I feel better after a good nights sleep.
I often also wake up sad-ish, and by that I mean, I never feel very positive when I wake up and don't want to get out of bed, when I don't go to work I will easily sleep all day and push my sleep cycle forward by 1-2 hrs every day.
I also suffer from slight anxiety before a night out or before birthdays with loads of new people. Basically I am not very comfortable with ''social'' situations, at work I don't have that problem at all, because with customers, I know my goal, what I want, and what has to be done, but it's different in social situations.
Basically in work environment I don't suffer from anxiety at all, perhaps because I've worked in more than one sector ( retail too) and dealt with loads of people on daily basis ( it's easy if you have a goal, eg. IT support (not phone support, but on location mind) you ask about the problems and move on to chitchat to make customer feel comfortable/establish rapport, or in business meetings, or in sales, or anywhere in business, we all have a goal, but in my personal life, I still get panicky/scared in various social situations and suffer from anxiety when lying in bed at night and can't sleep.
