Being "yourself" means following your desires and dreams. Not being a burning mess and letting the bad out, while keeping the good, your skills, abilities and good qualities locked in.

Nobody is meant to be in bad place... and being in bad place, emotionally or for real is not what make you you.

We change, we learn (hopefully). Repeating mistakes does not mean you are yourself, it means you are not learning. Dwelling on bad life means you are afraid to live rather than being true to yourself.

That's just my opinion.
