How can I continue to improve after a bad year?

I left my old job of two years cuz i was burnt out and losing hours and they gave me a pay cut. Got a new job the next day. Got out of an abusive relationship. Started workin out again. But still have a nicotine problem and a habit of having too many beers sometimes. And ion feel bad being by myself. Like i went to a concert wit just myself. Ion need no one there wit me and im happy wit dat. How else can i improve? Thanks y'all
