If you were in fact a prophet, you'd know it, and it would be confirmed by fellow prophets, just like in the office of pastor, after counselling, observation and training to understand the office of prophet, a service of confirmation is needed as is the laying on of hands in confirmation and prayer.
I take the gift and office seriously, and never move in the gift without prayer and a word of knowledge coming from the Holy Ghost. As a prophet, His spoken words through me have always been Biblically backed and time has shown them to be correct.
It sounds like you were confused and conflicted as to the gift and its working as well as place among the other gifts and offices of apostle, teacher, preascher, pastor, etc. But the truth about prophet, like the other callings are that they ate JUST THAT ..... a calling. My calling to the ministry was a no doubt event. And God demonstrated to me that this was where He wanted me. The same was trueabout prophet, later in the ministry, and like with pastor, I came to know, that I know, I was called!
I struggled because I didn't believe prophet was still an available calling, but time and experiences showed me my error in thinking.
I think you have seen your errors, good for you. I just want to say, if you ate called, you will grow to hold no doubts. Shalom.
