Not trying to be funny but try giving up porn. Porn, as other addictions, can mess up your dopamine system and give you feelings of depression, social anxiety, "mind fog" and other bad side effects...
"I'm one of those guys. The amazing part is that a year before I tried giving up porn, I even went to see psychiatrists and psychologists who diagnosed me with severe social anxiety disorder and depression, and wanted to put me on antidepressants, which I never agreed to.
When I went on my first no-porn/masturbation streak (~80 days) I started noticing the benefits reported by others. Today, on my 109th day of a streak, I feel happy, confident, social, smart, capable of meeting any challenge, etc., etc."
"I have experienced some awesome benefits. First off, I finally have energy again! I haven't felt this good since high school. It's not like I'm Hulk or anything, but I finally have extra energy to DO stuff. I spent most of my early 20's in a state of low energy and mild depression. Now that I've stopped [masturbating to porn] twice a day, I've been exercising, being more social, and generally enjoying life."
