Sorry to hear you're not feeling great courage but good that you don't want to drink.
Has something happened to trigger these feelings? How's work?
I get episodes of feeling bad falling which usually relates to how I am interacting with someone . I just really think about it or even step away for a while, if possible. I tell myslef I can't control what others say or do and then do something stress relieving-yoga, walk, read, even deep breathing. It is so important for me to have peace of mind for me this means regaining control of my thoughts rather than letting them slide and escalate.
Often things seem worse when short of sleep or under work stress. I hope you managed to get some sleep last night and perhaps feel better today?
