If you have add or are impulsive and you feel that is holding you back from starting to look for a job, take medication. (I took Concerta personally)
Improve yourself. YOUR GOAL AS A NEET IS TO MAKE YOUR BODY AS HEALTHY LOOKING AS POSSIBLE. The point is that self betterment improves confidence and lessens your social anxiety lessens. Trust what I say.
Keep your skin clean by exfoliating (I use baking soda and water) and then moisturize everyday TWICE.
If you are overweight, eat less (no high calorie foods). Exercise focusing on high repetitions and drink a lot of water to fill your stomach.
If you are underweight and a girl, you are in the clear, it's a good thing. (As long as it isn't anorexia or something, I personally don't have much help for that)
If you are underweight and a guy, like myself, drink whole milk (half a gallon a day, or a full gallon if you are serious about gaining weight) for a couple months on top of your existing diet. And 2-3 full meals a day. I personally recommend getting a big bag of white rice and stock up on chicken breasts. Do pushups and squats everyday and get into lifting.
I focuse here on nutrition because that is that core of your mental health and physical health. It will makes you think better and look healthier. Combine this with exercise and your social anxiety problems will fade away as you notice improvements. Soon you will put your struggles behind you and be laughing as your confidence starts a positive feedback loop. Post too long. Click here to view the full text.
