My mom still witnesses to me and still sends me the WT and Awakes. I throw them in the trash. I sometimes put the phone on mute and unmute it when I figure she is done witnessing. I was not DFd so perhaps she is counting her time.
As for college, all I can say is "IT WORKS!". Seriously, when you say you have to go to the library because you have to research something and no, you can't use online research, you really need to get up and go. As for FS, use school as an excuse. If you have to meet with the geek club to do it, try. Anything to not to have to go pound on doors will make it worth it. A big plus will be the friends you'll make.
I've learned that once I paid my bills, my mom was happy I could. It is a lot easier to preach to me when I'm paying my own way.
Good luck!!
