You've received some caring & consistent advice, Killimunati ... only to shoot down every suggestion. I understand the feeling of helplessness. But, now is the time for you to empower yourself, and take matters into your own hands.
So you may not be able to go to your mother to retrieve the documents you need ... your mother can mail them to you easily.
Other than that, I'm not sure what else you are really trying to ask for. Can you be more specific with what you are REALLY needing so we can address those issues instead of flailing about blindly?
We are all trying to embrace you ... please stop dodging us.
Edited to add: If you don't want you mother to go through your belongs then she never should have had access to them in the first place.
I think you will find that most of us enjoy a good puzzle ... but there are many pieces missing from this one.
Let's start all over ... what is your real question, Killimunati? We'll continue to help the best we can. However, we are far more limited than you yourself.
