Drinking for me was the "answer" to handling most any ill feeling and feelings such as you are experiencing. The rational thing was/is that it was no answer at all, but instead just added fuel to whatever fire occurred. It took time, but I found ways to deal with most any situation/feeling by doing "something else".
Exercise is likely the most important tool I use. It levels me out and decreases general anxiety and naturally provides a sense of well being when done on a regular basis. Sometimes I walk, read, bike or do most anything else to cope. At times I have found that I just have to acknowledge and just experience whatever is occurring. With a bit of time and not doing anything "counterproductive" such as drinking the ill feeling passes.
