I don't think I'm an extrovert, but, to be honest, I don't exactly remember my reaction to "being with people" or how do I feel after it. When I'm not constantly exposed to social contact I tend to relax and forget how exhausting it is. What I can remember now is that after a regular week of work/college I just want to be home or somewhere else either alone or with someone I feel absolutely confortable with.

So yes, I'm an introvert. I was confusing things and that "wow, I overcome anxiety this time" feeling. Adding to it that I had acohol in such occasions.
