<human>: For the last few years I've been struggling with depression and social anxiety. I've gone through incredible fluctuations in moods year to year. With these mood changes comes either a willingness to seek out my close friends to spend time out with them at the bars or my intense closing off into hermit like behavior. In the past year I've been trying hard to be more enjoyable to be around in the hope that friends will stay in touch. 

However, I've found that when I do go out regardless of how I felt in the moment I feel drained and angry and somehow upset when I get home. I thought this might have been an effect of drinking because I've had issues in the past with binge drinking so for the last month and a half I've gone nearly sober. But I'm now realizing that these feelings are still there even if I have only one drink and leave well before bar crawl situations. 

I will feel frustrated and physically exhausted even after a good night. I also begin to look back on the events of the night critically and angry, almost as if I'm looking for reasons to be offended. I don't understand why this happens and I wonder if it has anything to do with being a generally pretty introverted person. I can talk to others if I need to but I've never relied on friends to get me through the day. I mostly see friends as people to join you for big events or to help liven things up every three or four days. 

Does anyone have experience with these feelings or this phenomenon? I would appreciate any ideas or suggestions. I don't know how much information is relevant because I don't really know where to look for the source of the problem.

Can you provide a brief rundown of the text in within 3 sentences?
