Hi,
I'm not sure about the title of the problem, so I'm asking for opinion.

One friend of mine that I recently helped a lot and spent time with, sent me one photo:



To this new friend of mine I was pretty quickly open and honest. What she could do to me was to use some of mine weak spots, blind spots, to use my knowledge in our recent situation...
I guess I did a lot to help this person recently and she, in her weak minute, sent me this photo as a hint to my blind spot of my interaction with other people.
When someone ask me to do something, I jump and do it immediately as a form of help and to me as a mirror of being helpful and useful to someone.
To my parents I was good boy only when I did what they wanted me to do.
I also remember hiding somewhere in another room as a kid, in this rare moments, I felt safe, without a feeling of being a subject on which others could express their frustrations. All I wanted to be left alone, without being obligated to fulfill others expectations.
I felt guilty for the all things they had to do for me as a kid on a daily basis. I feel my birth trapped my parents to stay together.
Now I have a feeling, when you are an open book to a person, and that person figure out the psychological pattern by which you function, but that person will remain silent cause he has something out of that what for you is a blind spot.
This is what my recent 'friend' is using out of me.
But when you drag this pattern from your childhood, your subconsciousness, and you can't get rid of guilt of saying no to any person (a parent), they can ask you any type of a question they already know the answer, or ask for help for things they can do alone... and you'll jump and help them as a slave of this guilt.

Please any opinion, link or phrase that could lead me to better understanding my weak spot.
Thanks
