I didn't make any threats against them or in a Kingdom Hall. All I said to my Dad who isn't even a JW that they are making me feel suicidal to the point that I feel like shooting them because they are making me feel soooo upset or I just leave and never go back.
Thank you for finally telling us what issue concerned the elders. Why didn't you tell us this in your OP? Because you knew we would be fully understanding of the elders decision to consider taking out a restraining order.
I work in mental health and I will be perfectly frank with you: To blame depression and suicidality on making threats towards others is no excuse whatsoever. You made it seem like the elders treated you badly when you disclosed feeling depressed and suicidal - NOW you tell us that you told a third party that you felt like shooting the Witnesses. I am pleased your father (a nonJW) informed them of your threat.
It is good you are seeing a therapist. I hope your therapist doesn't beat around the bush and makes it clear that making threats to harm others is completely unacceptable and that you should stop blaming mental health issues for doing so.
