I need to fix my life

I really don't know what to do I am 21 years old and I feel like I have so much going for me but I can't stop spending money on woman online, findom in particular. I have already spent over 30k on this addiction. It would be one thing if it's fun and enjoyable but it's not, it's socially isolating. I have no friends none I don't speak to people my own age not men or woman unless it online and the vast majority of the time it involves money. I have payed for dommes, girlfriend experiences, cam girls everything. This social isolation has led me into radicalized alt right pipelines that fill my brain and I don't even know what is real anymore I am so socially isolated walking down the street I feel as though there is a glass wall between me and society.

I have been able to break every addiction I ever had going from drinking and smoking weed for months on end to cold turkey but jerking off and particularly spending money on woman seems impossible. I feel as though if I don't stop this now I might end up with a permanent solution to a temporary problem , it makes me cry when I realize years have gone by and I don't gain any new life experiences or hit any milestones that most People my age should be hitting. I don't know what to do. Please help me.
