Please get someone to help you rewrite your post...........

Much of that depends on the particular by-laws of the church and/or denomination.

Sure. You can complain to the landlord and/or the police.

Every judge is different. Retain counsel or get a PD. Not a DIY project.

Why would you ask lawyers who you can date? Ask your parents, and their parents if they are a minor.

It is legal for them to base the deposit on the prior tenant's usage.

I don't see anything in your post that would give rise to a lawsuit. Seems like the school did exactly what they should do. Perhaps there is more.

You can continue trying, or realize that the lawyers you have spoken with don't think you have a case worth pursuing.

You have no ground to sue anyone IMO. You have no "privacy right" in this situation.
