Will creditors come after my bank account if I am on SSI?

I had a consultation not long ago with a local bankruptcy lawyer. My mom went with me. My only income in child support and SSI. The lawyer said as long as that is my only income none of the creditors could do anything. If I got a job though they could possibly garnish those wages. Question is, a lot of the creditors I'm in debt with are department stores. Also,2 local banks. I got credit cards through them and could not pay them off. I bank at one of the banks I got the debt with. I got a letter from an attorneys office locally saying I had to pay them 25 dollars a month on the one of the bank debts, which is the one that I bank at. So I have been paying them 25 a month and the other bank, directly to that bank 10 dollars a month. Since my mom went with me she said the lawyer said I did not have to pay any of the debts as of now because I only have SSI and child support and they can't touch that. My mom said the lawyer said i had to keep paying the banks though. I did not hear her say that. So I have continued to pay the banks. I called that lawyer this morning and she said I could call the law office my bank has me paying off my debt at and explain my situation. She also said if I bank with that bank, they could take the money out of my acct if I don't pay. So if the bank can do that, why can't any other creditors I owe do the same thing? When I first saw her at the free consultation she said no one could touch my money because it was only SSI money and child support.
