I'm 18 and addicted, lost big today

Hi everyone, when I turned 18 i decided to invest into xrp to make some money. My parents were happy to loan 900£ for investment. This is a lot of money for an 18 year old and I guess I couldn't comprehend it. Then I learned about crypto casinos. Over the course of the last month I ran this 900£ to 3300£. I was ecstatic, felt unstoppable etc. every time I lost I just went all in and won it all back. Then today I didn't. I lost everything. I don't know how to feel. There is an aching feeling in my heart and I can't look at my parents in eyes without feeling immense guilt. I was thinking of all the things I'd buy with this money, and now I'm just thinking how to get 900£ back to show my parents I'm not a failure of a son.
