    I'm afraid that I could become the last man on earth if I manage to survive another couple millions of years from now.

    Humanity won't last forever and in that I'm almost sure.

    What really scares me is that maybe in a couple millions of years from now, I'd be the last human being on Earth provided that I really want to and could to survive this long and didn't kill myself long beforehand.

    You need more information. How old is the person? What kind of skills does the person have? How healthy is the person? What are the environmental conditions? If left near a major population center, and he/she is healthy and able to deal with isolation, I imagine quite a while. The could become a scavenger. There would be more than enough stored food, clothing, shelter, food, etc.

    It's generally estimated that the maximum age a Homo sapiens can reach is roughly 130 years. No one has come close to that yet, but advances in biology and medical technology could, conceivably, stretch it.

    Of course, we have a statistical problem, because all of the people who have taken their turn in the record books as "the oldest human" were born in the 19th century, so their records are not exactly trustworthy.

    Nonetheless, the oldest person alive today whose records are well-documented, Emma Morano of Italy, is only 117. And note that women tend to outlive men by quite a few years. So there are usually no more than two or three men in the top ten, and it's not unusual for there to be none at all.

    Homo sapiens is a social species that generally prefers company to isolation. If one human is the last one alive, with no other survivors, the psychological effect of the isolation might very well keep him from reaching his statistical potential.
