I don't know what to do anymore. I feel like such a fraud.
That sounds troubling. Have other people told you that you are a fraud?
No, but some people have commented that I come off this way.
Even if other people say you are a fraud, if it isn't founded in truth then you shouldn't let their unfair criticisms concern you. I would recommend ignoring them and believing in yourself.
I feel lost.
Have you considered professional help to get through this. A therapist or life coach would probably have some great suggestions for you. I think you should consider reaching out to one of them.
