Life is all about change. Like the tides of the sea. Nothing ever stays the same. If you can't be yourself around people then they weren't the the right one.
Comparing your life to others is a trap. You will never win. None of us can know what others lives are
really like. Follow you passion. Love yourself. When you love yourself life wont be so lonely.
When you are engrossed in your passions you may just find some-one who can appreciate you for who you really are.
