Whatever problems are troubling you now are deep rooted. Any attempts to deal with them in a superficial manner are useless, and drastic measures will only lead to more problems. Your situation is very difficult to handles.
For you it has never been easy to find a romantic partner. Your standards are very high ... perhaps too high. It is not easy for you to find an individual who meets them. You know this about yourself, but do not think that changing your requirements will alter your situation. It won't. It will only lead to romantic dead ends.
