In this life, no one can ever experience what you have experienced. We have different histories and different things happen to different people at different times. Even when the situation looks identical, it is never the same.
Do not let anyone tell you what he/she has faced in life either to praise himself or motivate you. What you have faced in life are unique problems and only you can fully understand them and praise yourself. How you conquered these problems are matter of personal experiences.
If you think your problems are heavier than the person beside you, then be in their shoes to have a clue of what they are facing.
Don't allow anybody make you feel what you are not. If you feel inferior over a matter, it is because you allow it not because you are an inferior person. These things are not truths about us. They are only cultivated habits that can be avoided.
Be the true version of yourself. Always look up and aim higher. You are simply you. The true version of yourself is you. Look within and bring out the you in you.
Be motivated!
