You need significant relationships with other people, you are too self centered and spend too much time on the internet , which you are addicted to. I guess you have no opportunities to be in contact with other human beings in your daily life but this is what you truly need. When you have no relationships, life has no taste at all anymore. Relationships give a taste to life and feelings. No relationships = no physical stimulation and development of the brain, of emotions. Our brain develops itself when we are with others -not virtual people- real people. If we arent, it ceases to develop, as do feelings and emotions, everything becomes darker and darker.
You should fall in love with someone, get an education, a job... And you should consult a psychologist, they re for people who suffer psychologically even if they look "normal" from the outside.
The roots of your psychological dizziness are in your childhood and the way you interacted with your parents and family. Only a big and deep comeback in this past with a professionnal can have an influence on your present and future. You have to modify your cognitions and behaviors. At 44, this will be a huge task, but you have nothing else to do anyway. There's no escape from this, so just do it once for all. Your survival is in question at this point. You have to un-learn, and re-learn more appropriate ways of thinking and acting.
If you do not have/develop meaningful relationships your despair will increase. We are nothing without the others. I'm not saying you need to party with people you dont know everyday, these relationships you have to develop have to be constant, deep and reciprocal.
Your life is grey, you need to put some colors in it.
You are not going to find this on an internet message board. Get REAL help. The attention whoring doesnt solve the issue at all either. But it's a clear call for help whatever the way you look at it.
By the way, you re in no way unique or alone. People like you are more and more numerous especially in our modern societies. You lack some basics and you have to learn em , even if you're 44. You have to re-start your development, right now you re obviously immature, even if you're 44 it doesnt mean shit, and you have to become mature with the help of a professionnal. There are people who spend their whole life and die with an underdeveloped conception of the world, why they re here, why the other are here, and how we are suposed to interact with each others. Most of the time a good education, from your parents or from some mentors of resiliency/development, some teachers, can lead you back fullforce in life. Find these people and dont care about "what the other may say or think", these people dont care about you, they only care about themselves and you should do the same. People who truly care about you will only advise you to seek help from a pro.
