do I? do we?

I think real hard about the person I am today, my weaknesses and also my strengths. what I can improve on, and what I can share with others that will cause them to be stronger somedays its really hard to find my strengths and what I can share with others I find my voices in my head telling me your so weak that I am such a burden to others that everyone would be better off without me that no one besides my mom would miss me but I'm told I'm the only one who feels this way but am i ? I believe we all at one point question our existence
