Assuming this isn't a load of BS, let's look at the obvious ideas. If we assume the law of causality prevents a time paradox, for the sake of argument, is it possible you are being "kept" in this timeline because at some point in these last 8 years you did something that would prevent your research from beginning? It could be something small. Perhaps the reason you are "forgetting" about the future is so you cannot rely on that information, therefore forcing you to return to your "original" memories, the first you's memories, so you can begin your research unaltered? If what you say is true, this advice is likely too late for this timeloop, but if you could create a way to remember how you once were, maybe you can "reboot" yourself and wipe your future memories. Sorry if it's a bit rambly, I'm just saying what comes to mind.
