Your desire to become functional (in regular society) consumes you and your wish to be on the rails of life others are on seems almost impossibly elusive! As if you don't even want to anymore whilst desiring to because the gulf is so wide. You almost know you can never get to where they are so dont know what to aim for!
My feeling is that any who have been disfellowshipped or reproved for sexual matters, or even just felt that their sexual feelings are being ridiculed, berated or questioned, may well be consumed by guilt (unless they actually are deliberately not bothered and just using the WT system)!
This guilt can cause long term CD in the way the human mind and biology link and respond in an ordinary healthy human! The mind may be willing but the conscience imprisoning biological processes (it can be that severe) disconnects it at the moments of expectation or perceived expectation to behave naturally and sexually in acceptable ways which may be pretty clueless about the subtlety of.
Also to further compound the problem can be self esteem - the feeling developed over time that one is not physically attractive to the opposite sex - conjured up by decades of JW bedroom rulings and detachment from affection due to one being deemed spiritually weak etc.
So at any point in a persons future where they approach intimacy, fear and rejection inflate the emotions whilst the eyes see what they have long wanted to visit! An inner conflict of shooting onelself in the shooter! lol - but very true and very painful (emotionally I mean)
Maybe there are other aspects than the sexual which have parallels but I hope you get a rough idea from the above of what I'm on about!
It disharmonises your thought from your feeling and constucts negative spirals within your core! A very unhappy person period - acting to others as the reverse and for their advantage where possible!! Oneself is living a 'given up' inner self!
This maybe of some use to anyone in despair:
Learning how to ground negative energies is a good coping mechanism ( some mange via distracting activities and if not via beliefs such as wicca)
And learning how to draw positives is a similar thing if you look deeper at some forums and ask questions!
