You owe yourself ihsaan. You owe yourself good sleep, a word of encouragement, good treatment and unconditional love. Everyone you know will separate from you at some stage of your journey except for yourself. You will enter each chapter with you. So be good to you!
Instead of saying, "I'd never commit that sin" say “may Allah never test me with it”. We should never be too sure of ourselves, so it is better to ask Allah to keep you away from it
