What you are asking, it seems, is whether you can become a representative payee, and if you do, will that disqualify you from receiving SSI benefits, that you are currently receiving on your own, for your own disability. You will be required to account for all of the money that you receive in this fashion, and show how you spent it for your Mom's benefit, only.
If that is the case, you will probably not be disqualified, form your own SSI, but to be sure, you need to speak with a lawyer near you who handles this kind of case. Use Avvo find a lawyer feature to locate one to help you.
