I am interested in people's nail mode, I have no luck with my natural nails, they can't take steel strings, so I use acrylic powder and liquid. What can you recommend?

I have been learning to play guitar for almost 3 months. I bought a classic with nylon strings. I used all sorts of Internet resources and training videos. And I recently bought an electric guitar because it suits my musical taste better. Now there are problems-the neck is too narrow, the distance between the strings is small, and the metal of the string is also too small.Accordingly, everything rings, just a finger touched the next string-everything went rattling.it just pisses me off. it seems that everything turned out well at the classics, but then it swam. Especially my nails couldn't stand it. But I remembered the folk methods of strengthening nails that I read jazz guitar tab and it made my life very much easier.
