Well, my mother put in as much effort as she dared. When I was young (9-12) I always kept to myself, but I did have a small number of friends. When I was a teenager though I was usually pretty awful to my mother as far as telling her to leave me alone. She was very kind and tried to help in any way she could, but I was being a roadblock. I saw many therapists, but was unlucky with some of them and started shutting down when I went to sessions.
Around 17 she at least stopped asking the whole 'when are you getting a 3DPD' line of questions. I had a handful of friends that I sometimes would have visit, so I'm sure she wasn't too worried.
Around when I turned 18 though, I became sick (not mentally!) and had to finish schooling from home. I straightened out my attitude because it was obvious she had been suffering for my sake.
I can stay as a NEET because I'm still sick, with no sign of it going away. I get disability checks and whenever she needs money I gladly give it to her.
I have a young brother that has his own emotional problems thanks to his father, my sister was born premature and has mental handicaps, and my stepfather is generally just being a horrible person by being moody, drinking, arguing over nothing, losing his job every now and then...
My mother has so much to stress over, I don't blame her for my condition. I was sorta odd from the start, and circumstance made things difficult for her as it is.
I've caught her crying alone several times.. she's fought hard enough, and she's still fighting every day for my entire family.
