> how can I learn to be alone without feeling lonely?

I'm not sure you can. Feeling lonely is a natural consequence of being alone, particularly for someone in your situation, who was used to having other people around regularly in the past but now doesn't.

The question is whether you think feeling lonely is a negative, something you need to fix, or not. (Some people don't, btw; there is no rule of the universe that says feeling lonely always has to be bad.) It sounds like, at least right now, you think it's something you need to fix. If that's the case, I think other posters here have given some good advice.
