Congrats on your sober time.
Are you 'working on' your recovery in any way? I see an addiction counselor once a week and she's been a tremendous help.
The other thing I did, and it was around three months, was I started expressing gratitude every day. At first I had to force myself to think of things to be grateful for but now it's habit and I'm continually aware of my blessings.
Sounds like you might need some support to get you thru those rough times. There's lots of that here, tho some face to face support might help a lot also.
