I'm feeling depressed after wisdom teeth extraction. Help?

Unsure. I'm sorry to hear you are feeling depressed, but is it possible thee are other things going on in your life that coincidentally are making you depressed at this time, or that you started taking some new medication (incl herbal or over the counter ones) that could have depression as a side effect? If you can't find out such a reason, please get a professional eval, because this is highly unusual.
