Addicted to Baccarat

Hi, I'm 24f and honestly I feel like shit right now. My boyfriend introduced me to this stupid game a year ago and now I can't stop. I get very excited whenever I see pairs, a tie and even a super 6. I ruined my relationship with my family, especially with my dad. He gave me a total of $6,000 only for me to gamble it all on online casinos. I have a job that pays well somehow. I promised myself never to gamble again, but I did it and blew 40% of my salary which my boyfriend found out.

I'm thinking of selling my phone as it is the only way I think that can stop me from gambling. I need advice about this because my boyfriend is against the thought of me selling my phone. I really want to be better this year and I want to save up.

Any advice would be very much appreciated. Thank you

Edit: I also have $8,545.57 debt that I don't know how to pay off. It's weird because I would often feel my hands shake while betting. I would also like to add that my boyfriend offered to manage my salary. But I'm worried because he is into trading. I feel so lost right now and I can't sleep.
