There is a difference between demo trading and trading with real money. It's an emotional difference.
Drive down the road, throw a one-penny coin out of the window every time you go through an intersection. It's easy! That's how demo trading feels, when you take a theoretical loss.
Drive the same road, but this time throw 100 quid out the window at every intersection. Do you feel like you want to stop driving? Perhaps you want to avoid intersections? That's the way it feels to endure real losses with real money.
4 weeks is not really enough time to learn everything that there is to learn. You will probably learn a lot more in the next 4 weeks of trading with real money.
My recommendation is to be very careful, control your risk, trade small and build up over time. If things are not working out, stop trading with real money until you know what needs to be fix.
