Will I ever get my life back? Will I ever find myself again?

Hi all.

I am 24, and have been smoking daily for 2 years. I feel like I’ve completely lost myself and my life is gone. I’ve stopped talking to a lot of friends and become very lazy & lonely. Before this, I feel like I was quite happy go lucky.

This morning I have quit, how long will it take to feel like myself again? Feel like I’ve completely wasted my 20s and lost myself. Will my life & me come back? Thanks all x
