(((Phoenix))) I get like this. I go and do something successfully, and I just want to wallow in the success of it.
Then all of a sudden other people are "demanding" stuff of me. I use the " " because usually they are just being nice, but for me that extra bit they are offering is too much so it feels like a burden. I get so worried that I can't cope with the intrusion that I become overwhelmed... I am working on a strategy to manage this at the moment by
1/ Being very aware that the "demand" is really just usual social interaction - and I should take it as a positive that people want to talk to me, or like me.
2/ Try to manage anxiety as it will always raise it's ugly head at these times.
3/ Negotiate further contact - which needs to be short, uncomplicated and in a quiet place. To help with this I often tell people that I am really stressed and tired from work (which is true) and therefore I would not be able to cope with anything to hectic.
I must admit that many people tend to take my response as a rejection, but I don't have it in me to reassure them that I am not rejecting them, that I just need to keep my life pretty simple at the moment. So it can be a bit of a double edged sword, but I guess that interpersonal relations are like that.
