As a former member of 'the Body' I can assure you that if you tell the elders all the reasons you can't return to the kingdom hall you will be labeled much more than 'spiritually weak' and more than likely will be DF'd for apostasy.
If you want your MIL and dad to see just how loving the Watchtower's shepherds are then you should meet with them and spill your guts.
It may wake your family up and they might leave the cult, and then again it may cause them to get closer to Geehover and shun you for the rest of your life.
It's your call.
Personally, I would ignore them.
