One thing I would recommend is to not force it. If it truly repulses you, forcing yourself to keep trying it will only make you hate it more. There's no hard and fast rule that you MUST like Scotch. Single malts can be very divisive, depending on your tastes. Personally, I cannot stand smokey, peaty ones, Islay malts like Laphroaig. That's not to say it's a bad whisky; far from it, it's a fantastic malt, I just don't enjoy it. I like the cleaner Highland and Speyside malts, like Glenlivet, Macallan, Glenfiddich, etc. I will also not discount anything without tasting it. Oban is a smokier whisky, but I enjoy it. I've even sipped on a Talisker on occasion, and the experience of drinking it is akin to sucking the fluid out of a piece of volcanic obsidian.
Also, if you don't prefer the Glenfiddich, it doesn't mean you dislike all Scotch. Look into the different regions and their signature flavor profiles to see if any others fit the bill. You may find you love a smokey malt, or you may find that you only enjoy those that have next to no peat in the flavor. It's a very personalized choice, and your tastes can grow and change over time.
Also, don't overthink it. I talk like I know a lot, and I admit I may know more than most, but when I drink Scotch and mull over the flavor, I am not analyzing its mouthfeel, opening, and finish. I'll use those terms to describe something, but in general terms it's either "that's fucking delicious" or "that's not for me." It's easy to sound like a connoisseur, but it all really comes down to how it tastes to you and how it makes you feel. It doesn't matter what the mouthfeel is, how it starts, finishes, or goes down; if you like it, drink it. If you don't, try something different.
