Why me?

Do you ever wish you could live the life of someone else? Someone perhaps who isn't struggling with anxiety, or depression? Everywhere you look there seems to be people with their life so together that it's painful to return home and see how your life is going. Sometimes you feel restrained be it by age, or gender, or even by something that you can't quite put your finger on. It really can feel like you picked the shortest straw in life. All your friends are beginning to become successful in life and you feel left behind.
Well I feel like this a lot. It can be really hard to shake feeling like this and see the positives in life and what makes you unique and amazing. This is me trying to push through victim complexes, low self esteem and trying to deal with things that stop me reaching my full potential.
