I was scammed

So, a few months ago I was told about people making money on feet finder and I was in a desperate position. So I hoped that selling my feet pics I'd get better financially. Well anyway, today this guy says he's interested in feet pics gives me his Snapchat so I talk to him on snapchat he says he'll give me $1200 if I buy $100 worth of Bitcoin and send it to him. Well anyway my head was saying this is a scam but I still send it I even made a PayPal so he could pay me. Then he says that PayPal will not let him send the money unless I send another $250 in Bitcoin. I couldn't afford the full $250 so I just sent him $167 well anyway he said I'd have to send another $250. I mean this is just stupidity on wheels like how dumb can I be like even typing it out I knew it didn't make sense but I was so desperate for money that I didn't even listen to my intuition. I was hoping that money would come in and then I'd be able to pay tafe well I just lost everything in my bank account. Well anyway I hate him I hope he burns in hell and I hate the fact that I didn't try harder at school to make the grades because I think it's my laziness and refusals to make myself better, that's the reason why I haven't been able to be employed. I feel like I'd never have been on feet finder if I tried harder and stopped being lazy I feel like I made so many excuses for my lack of independence and even now I'm not buying it. Maybe this is a valuable lesson in the long run but it cost me $420 to learn it. I will never let my brain convince me that there's no point in trying because I'm mentally incompetent and disabled. I'm not buying it anymore. It's total crap which lead me to stupid decisions that hurt me. If I was kinder to myself and had patience and just worked through it I would be further in life. I don't see the point in putting myself down selling my feet for assholes. I deserve better and I at least have some intellect maybe I can't organise things or have spatial awareness but all those things can be taught I don't see the point of abusing myself when people will do that for me. The lesson here is to be strong for yourself and trust yourself and have self reliance
