I first learned on a manual in the 1970's. Drove one for ten years before going automatic only because that was the best and cheapest used car in the ads the week I needed a very quick replacement for my manual car which died.
But driving a manual is grand. LOVED it. Once you master them they are as natural as breathing.
Some US friends of mine who had never ever driven a manual, used to say to me in horror " But it must be so distracting! They must be a bigger cause of accidents....." ::)They just couldn't understand how it becomes second nature to change gears yourself.
But it really does. As others have said here, it's all about the "biting point" where you feel the clutch engage, and then it's all about a smooth motion of both your feet, one of them moving up, the other moving down. Once you get that smooth action you're there. it really does very soon become something you don't even THINK about -- just like you don't think about how you are breathing in or out.
I now wish to continue driving automatics only because the last time I still had my manual car, I was getting tiredness issues (it's being looked into now) bad enough that yes, even changing the gears was becoming an issue for me fatigue-wise, and when I reluctantly bought my first used automatic, although I didn't really choose it, I was soon a fan of the automatic too, because with my fatigue issues it was like being able to rest (!) ...well, in a manner of speaking.
Plus I do so much stop-n-go driving in a very congested part of London that constantly changing gears iwould not be much fun anymore, to me anyway (to each their own). I do love the "less to physically do" of automatic driving.
I'm also taking my UK test in an automatic because with a nasty little London test route to have to deal with, I'm going to have enough on my plate just getting through the test showing safety and good observation, let alone not having a tiny stall on a bad hill.
But I did love driving manual, I'm glad I know how to drive a manual, and sometime if I feel like it I'll re-take my test for manual too, just not right now. But manual is a breeze once you get over that initial hump. Keep going slow and smooth with the feet and feeling that bite and you will have it in the bag forever after, believe me. You'll be fine.
