Losing myself

I have realised I have absolutely no interests, hobbies or passions that match me or that I am good at. I have simply lost motivation to do anything and all I feel is that I want to give up on this life because I see no escape. Anything I try that could potentially interest me I manage to ruin because I simply feel it's not for me. I feel crippled by anxiety and frankly any sort of challenge scares me: even playing a video game which is supposes to be fun. That's how rigid I am... No solution I try seems to work and all I do is exhaust myself and the people around me.
