30 days sober is great.
For being irritable and unable to relax - those things won't likely come to you naturally. I had to take time to learn how to vent anger in a healthy way and how to relax without alcohol involved. Give yourself some time and be prepared to do the work involved. Recovery is SO much more than not drinking.
You are planning on exercise and sunshine - great. Meditating and yoga will help you enormously. Hang in there and you will look back on this time and be so grateful that you persisted.
