"I need some help I got in trouble for ditching school the week before winter break i ditched to go skating"

As a teen, I too skipped school, it was a plan, i had the morning off, that was ok'd by my mother, but when the 4 of us went back to my house, we were suppose to be back in school in the afternoon.. None of us knew that my mother was going to be home for lunch from work.. well to say the least i got grounded a month. My friends were seniors and i was a 11th grader. So don't fret on it too much, almost all teens do it. Possibly even your parents.
Now about your grades, What are you lazy about? doing homework? Do you understand the work given to you? If your having trouble with not being able to sit still long enough to learn, Does the words look all jumbled up? i suggest you talk to your parents. Let them know this, they will have a Dr. examine you, just to clear out the medical possibilities such as dyslexia or A.D.D. Once you find your clear to go on. Now is the time to buckle down, do your class work, your homework. I know the idea of being an A student isn't popular, but being a Medical Dr. is. It has to be like a passion,(like wanting a piece of Pizza so bad your drooling just thinking of it) you have to do what it takes to reach it, its not going to be handed to you. So don't care what others think, when you leave HS the people there don't really matter. They don't have to live your life. You do. So sit down and write you goals, then when you finish one go on to the next. Start looking at Medical Schools, get information, what grades do you need, classes in science, chemistry, math is important. Don't depend on anyone to do the fact finding for you, its your dream and as they say, Just do it...

You won't get help with the former here. We can't help with the former, and have no sympathy with it, anyway. You could get help with the latter. Basically, you need a different group of people to hang out with . . . or none at all. Seriously, I spent the first two and a half years of my high school alone, no hang out group, exactly because the only ones I ran across were screw-off doofuses. I didn't want to be around them. I had a friend who went to the same school and he said that how he ended up with the druggies was that they were the first group he came across and they invited him over.

Those are your choices, sometimes.
