Hello Friend, Good that you are seeking a help. Unstable mind is a sign of anxiety. No worries. It's just like any other physical illness and can be addressed with a counseling session. Just share your emotions and feelings with you friends or family members you care about you. Don't hold it with in you as it my aggravate. Still if you need help then reach out  to any psychology counselor locally or you may reach me online for further evaluation.
