Crazyhorse...stay focused on making a real life for yourself, even though at present you are with your family and are subjected to their wishes.
Settle this issue in YOUR mind, that you don't wish to ever be a MS, and make your peace with that thought. It's important to hold your own core principles that guide you no matter what others pressure you to do. You know TTATT and realize that accepting any appointment is the same thing as willingly placing your foot in an animal trap. Even if you manage to free yourself, you will always bear more pain and scars by succumbing to their pressure and pleadings. Remember they are not pressuring you to improve your life, but to improve theirs.
Borrowing from a US campaign to keep people off drugs: JUST SAY NO. Then go on about your life, knowing that they may well pester you but you never, never have to give in.
