The only way to avoid DF'ing and still have people treat you like ahuman being as well as allow you to fade is to show repentance(fake or otherwise). There is no other option. Faking suicide and depression just leads to people thinking you are crazy and rumors of it spreading like wild fire. Imagine what happens when these elders talk and it becomes common knowledge that the person is suicidal or depressed. What about your meds? What about constant visits from elders hoping you aren't slitting your wrists? Just not worth it.
Repentance is so easy to fake. Just go in there looking dejected and and never let your words focus on you. Just keep saying how upset you are that you hurt Jehovah and how that causes you to change. How awful and sick you feel that Jehovah's name is dragged through the mud. How it hurts you to know that those actions you have engaged in will make the organization look and how badly you want to make this up to Jehovah. You would be hard-pressed to find even the most evil of committees to df you. As stated even if they do and you appeal it the possibility of you having it overturned is much much better than if you act like you are suicidal.
