It's normal to feel crappy in early recovery. It will get better, the longer you're sober.
The one thing I started doing to bolster my recovery was to practice gratitude every day. Even just one thing I was grateful for - no matter how big or small. Practicing gratitude made me happier too.
Give it a try.
