I am introvert too and my home is my sanctuary in terms of character, creativity, focus, mood and it's my recharging place. However I can be quickly discharged and become morally exhausted by simple phone call but it depends on what tone I am being talked at, on my mental clarity and quickness to understand what I being told, on my ability to resist fear-based anxiety and avoid potential panic attack where I become locked up, being unable to be myself and thin rationally. That's one case which can get through my sanctuary and get me. There's another less probable with visits to my door by strangers.

Most often it's when I am away from sanctuary that I start discharging slowly. I try to avoid places where conflicts might arise and stupid situations might get perceived on a too deep mental level that can discharge me instantly and it will take at least half day to recharge. This also applies to above situation and usually next morning I feel better.

Like @jk2833 said about self-analysis of conversations I have this as well. I often think about such situations and how will this be in future. How will I live with that and how my career will be. I often recall past situations that resulted in PTSD or something that made me feel bad enough that day that I can't erase it from memory even after 7 years. I guess I look on other "normal" people and maybe envy in how I would like be like them because problems that I have are joke to them. I keep this self-analysis (usually when being stressed or having anxiety because this takes me back to past) and criticize myself why when when something happens every time I fall for it again without learning the lesson and become better. But I think each has his own probems in this life even if we desire to switch places with others but maybe others have problems that we would not be able to deal with? Maybe our life circumstances are consequences of our karmic past doings and we are here to bare the punishment by suffering but eventually becoming stronger versions of ourselves by finding our places where we belong?
