It's possible that anxiety, irritation as well as impatience are part of your "baseline" personality; perhaps drinking was how you coped with those feelings. Take away the alcohol, and you still need to deal with how you feel when you have these types of emotions-only they may feel amplified right now. Take some deep breaths. Go for walks; outside in the fresh air if possible. Try to get good sleep as lack of sleep can make anyone feel irritable. Maybe this isn't the best time to tackle big projects.
