Inheritance, Medicaid, SSI. What does one do with inheritance in order not to lose SSI and Medicaid benefits? I am in Texas

I will be inheriting a large amount, around $100K or more, sometime in the near future. I am in Texas and have only been receiving benefits for 4 months. I am 43. I am concerned about how this will affect my SSI and Medicaid benefits. I don't want to spend all that money as I have a Schizophrenia and will need access to that money, so I don't want to tie it up, but I have been reading that the only way to not get my benefits revoked. I currently live with my family so I don't pay for much. Does this situation warrant an attorney or can my family open something to keep this money safe. I only have a mom and sister as beneficiaries. Thanks for help!
