I know you dont care but I’m just a week short to 5months

I was diagnosed with cirrhosis and I have been sober since November 7th. I feel like a different person and I don’t know who I am without drinking. I generally don’t feel happy about anything! How can I kick this feeling? My drinking became out of control when I found my husband cheating on me I was devastated! Now I’m divorced and lonely. Any advice is appreciated
