Hello, it sounds like you're having difficulty with asking for help from the teacher. My best advice would be to message your teacher and ask them the best way to ask questions about the material. If you can't ask questions during class, then write down your questions and ask them later. You can write down what the teacher was talking about while you had the question, the date and time you had the question, and what subject the question has to do with.
There are also many online resources for answering the questions yourself. I'm not sure what class you're having this problem in, but looking up advice for that specific subject could be helpful. Let's say you're having difficulty understanding linear equations. You could look up examples of linear equations and how to solve them.
One last thing I'd like to give advice on is motivation. It's important to stay motivated while learning so it's easier to work through the curriculum and understand the material. It's very hard to stay motivated when you can't even understand what you're learning! Make sure to remind yourself that you're doing the best you can with what you have. Promise yourself that if future problems like this arise, you'll take action to solve them like you are now. Be willing to ask questions to your teacher and fellow classmates to maintain hope and a sense of community. Sometimes breaks are necessary, but make sure you're not using breaks to procrastinate. If you're having a mental block that's keeping you from studying then tackle that after your break.
