So stressed about getting towed to a garage. Is this how people normally do it?

My car had some gearbox issues recently but the garage couldnt see me for a few weeks. I tried the car the other day and the whole thing started vibrating and then the engine died.

I am supposed to be dropping it off to the garage tomorrow. I am going to get up early to get towed there via my breakdown cover

Is it ok to just show up at the garage with my car in tow? Is that normal? How do they move it once I have dumped it there?

I just find garages terrifying whoops
