You are unique, you are you. Love yourself for who are. R espect who you are and people will respect you. Have fun in life, don't base your future on your past. It's called a past for a reason so let it go.
Mistakes are mistakes, choices are choices.
Never hold back on what you want. God sheds light on you everyday giving you new ideas for many problems you may have. But above all know that beside anything in the world living your life is more important then anything in the world. More like living your life like you want. Besides that, you must do what you want with your life but be who you are be yourself.
