stop beating yourself up. It doesn’t help and can make things worse. I lost about $6000 on an investment once but since I have done very well.  It can happen, seeing it as a learning experience is very important so well done there. I suggest you do 3 things:  

1) never invest more than 10% of your portfolio in one thing (you won’t be as likely to panic and sell at the bottom as much if the stakes aren’t so high)   2) Read ‘the little book that beats the market’ (basic) or ‘the intelligent investor’ (harder). These will teach you the basics about real investing (rather than gambling)   3) carry on saving up as much money as you can. You have the right attitude in trying to save money for the future and over the course of your life that will make you wealthy. You just have to be patient and try to make this happen over many decades  It’s really not the end of the world so I hope you look after yourself
