Ok, first of all I want to talk to you about the drugs. I've looked at some of your other posts, and I can tell that you have had a really tough time lately. When traumatic events happen, sometimes people turn to drugs because they think they make them feel better. In reality, the sense of feeling better is false, and in the end these people end up more depressed because of the drug use. You need to address the drug issue right away. If you keep using, not only will you be potentially damaging your body, but you will have wasted time, put yourself in bad situations and places, and wasted money. Not to mention that marijuana is often considered the "gateway drug" because people can get curious about other drugs. You are already using prescription drugs, and now you are curious about mushrooms and LSD (which are absolute poison and VERY damaging to your body!! ) I think you need to work on kicking the habit and getting sober. I think you should talk to your parents/guardians. If you don't want to talk to them, talk to your school guidance counselor or nurse. It can be scary to ask these people for help for drug addictions, especially if you don't know them well. But, that is why those people are there -to help. If you tell them that you need help quitting weed/pills, they won't be angry with you or yell at you. They won't have you arrested. What they will do is put you in touch with groups that can help you, get you a counselor you can talk to about the drug addiction and past events in your life, and work with you and your folks to create a support system for you. They won't tell other kids that you are using. If you don't quit using the drugs now, you are setting yourself up for a downward spiral as you get older.
Second, here's the thing with cheating. You might be getting better grades on tests right now. But, what happens when you have to take the graduation qualifying exams or the SATs/ACTs? Cheating may be getting you by right now, but in the long run, you won't be able to keep up the act. Not to mention that, sooner or later, you will either get caught or someone will tell on you. Then you will have disciplinary issues at school as well as problems with grades. I think that you should give the tutoring another shot. Make up a list of things you need help with before you go. Tell the person how you learn and remember things. For example, if I write something down, I will remember it. But, if I read over it once, I probably won't. That's just what works for me. Everyone learns differently. With some of the stuff that has happened to you, do you think depression might be the cause of some of your problems? I think if you talk to your doctor/parents and give them the big picture of what all is going on in your life, they will be able to get you some help. Please consider giving counseling a try. Here are some websites about drug use:

I'm not trying to boss you around or preach at you or anything, honey. I just know what it is like to be overwhelmed by life, and this is just my opinion of what might help. I know you have it in you to stay sober. It is very important to have people supporting you while you are trying to quit drugs. Good luck to you and God bless! :)
