Hi DASMASTER. World of Warcraft?
Your circadian cycle is off, due to your late sleeping schedule.
You may also be exhibiting some early signs of depression.
Developing relationships and a wider social circle is important, as I feel your transition from your previous employment situation,may have caused your social life to decline.
Pulling back on masturbation might help, but I don't personally see this as a big contributing factor.
Singapore is truly a beautiful and very colorful city and you can create
the right circumstances in your life, so you can enjoy the numerous things the city offers. I spent a week in Singapore and absolutely loved it!
Maintain a better schedule,get out more, join a club, a gym, engage in activities which interest you(in addition to gaming,if that's what you're into), optimize your diet (the variety of foods there is crazy!) and
hang out with people who are fun and influence you in a positive way.
Hey, DASMASTER, my intention is not to criticize you and your choices,
but to bring to your awareness some facts,some of which I suspect you have already considered.
Also check your Vitamin D3 and magnesium levels
