I don't know who I am anymore

every day whenever I wake up , I start to feel weak and sad inside as I just look at myself in the mirror but then I even ask myself who am I?? Am I the person that might be a successful person in the family as I will have a good life but what I really think of the person that I am is ........ always sad , no energy, trust issue, misses someone, failure, forgotten, person that will always get hurt .... I don't know who I even am , I know what I do but I don't know who is that person inside me , am I the person that writes poems , person that might be bad, The person that thinks that she don't exist, the person that will always trust a friend but In the end they become fakers WHO EVEN AM I ...I...I...I NEED TO KNOW WHO I AMMM
