Struggling with adulting

Hi, 

I feel apprehensive about writing this but here goes. I am a vulnerable twenty-two year old woman on the autistic spectrum. I can cope relatively well with most things, but there are still certain factors I have difficulties with. I need to socialise, but I also do not want to, and I also struggle to do so. I am content in my own company but my mother thinks it is something I need. I cannot manage my money or really cook for myself, and I just cannot make myself aware of my surroundings. I have dexterity issues as well, and I am trying to get employment. Any advice? 

thanks.
