Olymp Trade — I'm not sure if the problem is with me or not

But there are 2 times now that I've lost my money trading with Olymp trade. I was trading on demo account, and was doing very fine, so I decided to deposit the equivalent of about $130, which is a signfiicant money for me, into Olymp Trade. I continued to trade with my demo account, to check the market movements, but it turns out I was now trading on real account, and the money I invested was almost totally lost by that point. CHECK the money, where it got deposited, and what you are trading. Difference between real and demo is not obvious enough, In my opinion.
Thank fully I didnt lose it all but I lost almost $60, and at that point I started trading knowing it was real, which was very scary to me. after a few sucessfull trades I started to lose, so I decided to double down, and lost mostly everything. I have withdrawn only $20 back, and now I don't know what to do. I might contuinue trading here but something needs to change.
