Yes, I know all too well from the WT the dangers of social networking...LOL. I do tend to look at some of the things that I'm doing as boring, I'll give this some thought though. Thanks, and peace to you and yours as well.
While you may view college as boring, I'm sure your know it's a great accomplishment and something to be proud of- consider posting pictures of small milestones along the way, such as a snapshot of a good test score, final grade, the book cover of a new class your about to begin. You can apply this approach to just about anything you are doing throughout the day, weeks or months. You said life is a breath of fresh air, maybe you can somehow show that through your post. For example, take a quick pic of the current skyline, when you encounter such moments, with a simple caption, "My current view"- if this fits your personality. Show them from a distance you are good.
As time goes on, it could be therapeutic to look back over your postings. At the same time, to a certain degree, it keeps your close JW family on the emotional hook. Don't let them off easy.
I am not friends with my children on social network. Before, I started waking up to TTATT, it would trigger something in me, when other non-witness friends and relatives would tell me about something they read or how proud they are something on my child's page. The trigger had to do with the fact that the things my relatives and others would mention were normal everyday things but, they are not always viewed that way in "JW" world. Things, that interest them and reflected their real personality and growth, like a few lyrics to a song, a picture of a poem, a picture of a fun time they had with friends, a trip they went on.
Parents naturally want their children be happy, do well, and to be proud of them. I started asking myself, if everyone else is noticing and acknowledging these things about my children, how could I not? What is wrong with this picture? Maybe I needed to reevaluate? Its sort of peer pressure, if everyone else saw good, then maybe I'm wrong?
I said all of that to say, it could trigger something in them, even if it's deep down (for a split second) to see their child doing well and accomplishing something as significant in life as college. If you are friends with them on social network, they will see other's positive comments on your page, if you are not, they will hear it through the grapevine.
Don't let them checkout easily. Worst case they will know you are doing just fine without the control of the WTS.
