Do Dependent, Survivors And Disables Getting Social Security Have to Limit Their bank account to 2000.00 or less, like SSI?

Anyone know if the Social Security has a section on their official site that talks about, explain does a disable who is now getting no more SSI. But is still getting Medicare and Medical benefits, and getting Social Security each month Still have to limit their account, like people getting only SSI? 

Because from what I know is that I'm consider a Dependent, Survivors And Disable. After my dad passed some time last year they sent me letter say my SSI is 0.00 and the reason how it got there. Also now there more on Social Security. The letter head even say Retirement, Survivors, Disability Benefits. Before my dad passed away I was getting a share of his Social Security and SSI, for so many years. With help from my very first Therapist

So where  can I find information on their site Do I have to limit my account to 2000.00 or under, like someone fully getting SSI only. So that I will not one day, lose my  Disability Benefits and payment is stopped till spend some of the money?
