Parents took $6000 from me without my consent. Resulted in homelessness and prevented university education. : legaladvice

I live in Alberta, Canada. About a year and a half ago, my family got a huge surprise from my great grandfather, who gave us each $5000 with the exception of my mother. I was 17 at the time, and my mother and uncle went to the bank with me to set up a joint account between me and my uncle since my great grandfather wrote the cheques in both mine and his name for some reason.

My father, who was an alcoholic at the time, stated that it would be best that all of the bank cards of the newly created accounts be in his and my mothers hands so that we wouldnt make reckless purchases. At the time, I didnt mind since I was planning to save the money for university, but the main reason I gave the card to them was because my father was not one to cross. Hes done things to me in the past, and ive been scared of him since.

All was fine until a couple months later when I decided to pitch into my savings with my job, only to find that the $5000 was gone through multiple purchases.

The tap function was on the card.

I confronted my mother immediately, away from my father, and she agreed to pay back $400 a month. However, this only happened for three months. Around the same time this started, my great grandfather, unaware of what happened, sent another $5000. Due to a plane ticket I bought to see my gf this August as well as a $500 slash to my paycheque, I was left with about $1000. However, after we transferred the money into my brothers account to keep my father as calm and stable as possible, his account was locked, my mother refusing to open the account.

I burst under the pressure, and was given the boot. While I was in the homeless shelter, i kept asking for the $1000 back to get shelter to find my mother already unlocked the account and gave it to my father.

I had to drop my classes in high school right before the diplomas because of this. I was unable to get a credit card approved by the bank for application because of the ridiculous transactions, and found that my great grandfather was going to send another $10,000 before he learned of what my parents did. A couple months later, i was let back in, but now theyre telling me "its gone, money is the root of all evil".

I lost my girlfriend after cancelling the trip, lost my university aspirations, and lost much more that id rather not reveal here. What should I do?

UPDATE: After seeing all of the suggestions here and seeing just how many people apparently have my back, I decided to leave the house and go back to the youth shelter while I get myself a lawyer and gather the necessary evidence. Thank you all, I never thought this would blow up like this when I went to sleep last night. Knowing a couple thousand strangers have my back seems to give me more courage to go about with this action than I did before.

You see, I have about $650-700 in known debt right now, and they're asking me to pay $250 a month for a room even worse than the unfinished basement I was sleeping in before, and giving my mattress away, as I found out just now during the moving preparations. It's still $500 cheaper than the room I paid for per month after getting out of the shelter at my friend's place, but it doesn't feel right, especially with how they're consistently acting as if what they did was nothing. If you guys have any more advice, I'll be sure to take it and update you all with the situation.
