I’m just broken,lonely,depressed,sad…..

I don’t know you, but I suppose you don’t have any real purpose in your life. That’s why you’re feeling this way, and everything around that breaks you down is not a cause, it’s just an amplifier of your inner discomfort caused by the lack of life purpose. And the only real purpose of any free human being like you is to develop yourself: physically, intellectually, by improving your self-confidence, social skills and any other abilities you want.
Don’t be affraid of losing. Any successful winners lose a lot, but what distinguishes them is that they are able to stand up and go further. Even after thousand fails something that is done well is already a manifestation of your efforts and it will make you feel significant.
