I tend to run into this a lot myself. For me I tend to take breaks and do some other things. Sometimes those other things, whether they be playing games, listening to music, or watching videos, could sometimes help give me ideas of what to draw. A break could even clear up your mind. It’s different for every person though.
Some people will continue to draw without inspiration until they draw something they like. Or they give themselves different motivations to draw, like setting goals of what to draw or drawing to get paid. If you want you could possibly try to set goals for yourself. Maybe this could get you motivated or inspired to draw.
If anything though you can just draw some random doodles. They don’t have to be about anything specific. Just some thing to pass the time and help motivate you. I think it’s best to try not to stress so much over this. A lot of artists go through these kinds of artist blocks but eventually we break through them, no matter how long it takes.
I’m sorry if this doesn’t help, but do your best and relax when you need to.
