Praise yourself for what you do well, and have faith in your future. Tell someone about the abuse. Sometimes just talking about the abuse can make you feel better. At other times, an adult or friend might have useful advice or be able to offer help. Be careful with alcohol and drugs.
Many people use alcohol and drugs to deal with tension or pain.
Unfortunately, they'll only drain your energy, keep you helpless, and affect your ability to think clearly. Try to drink or use only in moderation or avoid substances altogether. Relax and play. Relieving stress can improve your ability to communicate and make decisions. Physical activity can increase your sense of well-being.
