I bought a PS5 a year ago and still can't get used to the controller - what to do?

I bought this PS5 a year ago and I still cannot get use due to the controller. I am used to using a mouse and speedpad for videogames, and the controller feels clumsy and awkward. I've not used the PS5 in 8 months as a result and find I have no desire to do so. Any ideas, or should I just trash it? Right now it is just gathering dust.

Thanks to all who are answering this. I hate to waste $ 500+ on something I cannot use, but right now I see no alternative.
