In my opinion, there is no doubt time travel is possible. Why do I believe this? Well, it’s because we know one hundred percent that superposition is real on a quantum scale.
Time travel into the future is definitely possible (and easy, you're doing it constantly). Traveling to the past is a different story. For one, you'd have to explain the fact that the observer traveling to the past sees a violation of the second law of thermodynamics. Which means either relativity or the second law (or both) are violated.
Of course, if instead of you, we're talking about a subatomic particle, then sure. They do crazy shit all the time. There's a bit of a gap between them and you though
