AvPD (Avoidant) Do shed some light.

From childhood, i am having Avoidant Personality Disorder. I went to the doctor recently & they confirmed it. But one thing i want to understand is even in empty house, my brain keeps on searching for signals of fear. Due to this i can't focus on any task or work. Surprisingly, from childhood i have avoided work and relationships even with my family members. I get exhaust early even in thinking about that task(Shh... Oh My God, it is so complex) & also when i don't get what i desire(in case of work). For eg:- 1. If i have to find a spoon and the spoon is just before me, i will look atleast my times from corner to corner & i will not find. And after that i get exhausted. 【But while searching or scanning through my eye, i cannot just check one spot at a time i.e. while incompletely checking first spot, i jump to another one】 2.While reading book, same thing happens. I read one to three words but jumps to another word without even finding the meaning of previous words. Do shed some light.
