On move 34, I had a wall on the upper right, and placed a stone on the right hand side.

White attached to my single stone (violating the "don't attach to a weak stone"), between my stone and my wall, and still maanged to get out. 

I am finding a lot of difficulty dealing with stronger players making what seem to be overplays (e.g. attachments in my region) and still being able to get out. I then got frustrated and made some silly moves, and ultimately white wins by resign.
