Please have faith on God and yourself.Omit negative thoughts.Learn to sail through the struggles of life, not run away.God will not be happy with the negative thoughts of committing suicide.We all are born for some purpose and purpose is to do the best.Practice slow deep breathing, relax, Watch King's speech movie if you can and will explain you it is anxiety, nervousness which is causing stuttering.Pranayama will help you a lot, may be start with bhastrika.Simple ,slow deep breathing will calm you.Practice simple meditation,lying down on the floor, surrender and pray before God for inner peace. Blessings
