Why do i feel like I'm lacking???

[Lordreyna18]

Ok so I'm just about to start cna school I havent been in school in two years, and I still am feeling worthless like I'm not good enough. I'm a college drop out as well as a early discharged ex military. So I guess I haven't accomplished anything and I just really don't want to mess this one up. And sometimes I feel that my own self pity makes me incompetent in my own relationship as well as insecure. And I'm not sure how I'm going to finish paying for the school I have enough til the third payment but graduate a month before that so I'm hoping that it won't take long to get a job as a cna but I guess over all the point of my venting is can I do this with my feeling of this unaccomplisment within myself? And how do I make my time not feel wasted or like I'm not doing anything?
