Doubts That Come Once In A While But Never Truly Go Away

I'm not sure why I feel this way today. I feel that I'm not the right person to do what I'm doing for a living now. Or maybe it's just that this job doesn't suit me. When I first started, I told everybody that I'm fine with the job. "Everything's good!", I'd tell them. But now after almost 5 months in it, I somehow feel like it's not the kind of thing that I like or want. Or maybe this is just one of the bad days that lead me to doubt myself. I know who to talk to about this kinda problems but that said person ain't here to listen to me anymore. Oh well, just hoping tomorrow will be a better day. I gotta start figuring out what I truly want for my career, though.
