How and when did you truly start “living”

Example. I’m 22 and was in a majorly down mood for the past 7ish months but this last month i’ve noticed a change in me and I noticed that recently i’ve started waking up day after day with more energy and a lighter heart also my outlook on life is seeming more colorful. I’ve taken a liking in reading and cooking. I’ve quit smoking and drinking and am working out a lot more and most days I’ll look around when the sun goes down and just smile a little bit. I feel like i’ve just began living
