My sister and her husband have been taking my mom's money. Mom and I have statements to show this. Where do I go for help?

I have begged my siblings to audit mom's accts...they won't, they won't even listen to me.. this situation is so much more complicated. Steven King could make a great movie over this story line....I have been shut out, none of my siblings talk with me. They moved mom into a care home where only my siblings can visit or communicate with her. Not even her grandchildren can communicate with her. She can't call me and I can't call her..I live out of state, I was the closest with her, my sisters hated that..here is the kicker....my sister and her husband that took moms money (well pver $80,000) they told the whole family.....that i took it!!!!!!! In my mom's will, I have been cut out and without telling me or showing any documents. Statements etc...it is written that I owe $135,000???? Is this legal? My mom wanted this changed, siblings wouldn't let her...they put a lien on my house!!! the lien used to be in my mother's name, but now it's changed to her living trust? My mom didnt know anything about the lien, she tried to have it removed. They wouldn't let her.. now they tucked her away in a care facility for memory care!!!! My mom is 90, she does have some memory decline, but she is sharp..my sisters have everyone convinced she has severe dementia? With no diagnosis? My sisters husband said this to mom and i......Anna, we now know the key to you living a long life....is Mary (me).SO.....WHAT DOES THAT MEAN!!!!!so now we cant see each other..last time I spoke to her was December 23rd..I miss her. I have done nothing...I haven't taken anything from her...no one will listen to me.Where do I go for help?what kind of atty do I look for?I've called when I start to tell this cluster....they say that they can't help?
