Do these sentences sound natural?
Sorry, I talked too much about myself only. I didn't ask you how have you been so far. It's been more than a week since the last time we talked.

I'd like to shift the focus of conversation to my friend after a long interval, are the above sentences good for conveying my thought and do they sound natural?

Answer

Let's change the first two a little.

I sorry I talked too much only about myself.

I didn't ask you how you have been lately.

Answer

Hello, Shao.

Sorry, I've talked too much about myself OR I've been talking about myself for way too long.

I haven't asked you how you've been so far (OR depending on where the 'so far' actually goes, you could also say: 'So far, I haven't asked you how you have been'.).

Your next sentence is correct but you could also say: 'It's been more than a week since we last talked'.

After a long pause, I'd like to concentrate on (talking about) my friend OR 'I'd wish to let my friend talk'. (To be honest, I was confused with what you meant here that's why I gave you two possible options).
