Of course it is normal to feel the depressive feelings you are feeling in the sterilized culture of Taiwan. You are in a place where you feel isolated and have few people that understand you and so far as I know, you do not even speak the local languauge. As I told you, I have been to Taiwan and it is not much different (to me) socially than being in the United States.
When I am in America I spend about 95% of my time being depressed. Now I am typing you from Chiang Mai, Thailand, which is not even a very good "mongering" city as such cities go--certainly no Angeles or Pattaya or Bangkok--yet yesterday I had a date from the OK Cupid web site (I have been on this site in America for 3 years and not had a single date from it), the night before a young woman shared my bed (for free) and this afternoon I am getting an oil massage from a young lady that another lady wants to introduce me to as a potential girlfriend. After just five days here I had a drama-filled Thai girlfriend whom was a great f**k and here in Chiang Mai I can go to a whorehouse or massage parlor anytime I want--so the burden of going without sex is lifted. Not to mention that I have met some really cool people, both farangs (foreigners) and Thai--the Thai woman I had the date with yesterday was a vegan and we ate at one of Chiang Mai's many vegetarian restaurants. I have made acquaintance with many people and because I can speak Thai I have many women flirting with me who otherwise would probably not give me the time of day.
Am I happier here--Fuckin-A I am happier here. I could live contentedly here for many years and probably could find a quality woman within a year or two while f***ing my brains out in the meanwhile. Location and how you click with a culture matters a great deal, and I did not click as well with the Pinoy culture though it was okay. I am the opposite of Ladislav who lived here and did not click well with Thai people or their culture.
You probably need to make a move and plan your trip to China because otherwise you will probably sink more into a depressive funk. It is quite normal given your lack of sexual, lack of connection and feelings of being misunderstood (which are real feelings) by your family and the culture at large.
Remember, it is not YOU--it is THEM!!!! You are just in a place that doesn't fit your needs and it is beginning to wear on you. Find a place that fits your needs and the rest will take care of itself.
Wishing you the best,
