Just to be clear folks, while I do have many similar feelings I did not start this thread.
Anonymous,
Low self esteem is talking in all of that. If people are saying something that sounds nothing like you its not because they are the ones who are blinded by self esteem issues.
I personally am accused of being a 'good man' - I never feel it, never relate to it. I do, however have a few decades of therapy under my belt and my therapists (plural - this old elf needs lots of help) tend to agree with all of those others. If a professional tells you something based on their professional opinion you just have to go with it.
To a point we all are seeking to depend upon another human being for our happiness. It is what humans are hardwired for. And all of that hard wiring is to insure the survival of the DNA. And in truth, most people are, in general terms, happier in a relationship than being single.
If you are at the point where you are calling for help (starting this thread is a call for help) then its time to seriously consider getting a therapist.
I think there are issues here, and they are most likely not as bad as you think they are. A therapist will help you to understand you better, and if you need tools to cope, or deal with or even chance some behaviors a therapist can come up with suggestions and you can find your life tools that work best for you.
Furthermore, I think a therapist will be able to see your 'problem' and tell you if you are falling within nominal parameters of human experience or if you are crazy.
Understand, most humans wear masks. We all have fears, self esteem issues, a desire to pair off and find that one special person that completes us. We all get lonely. Sure, most of us won't say anything, slap on a happy face and pretend to be doing just fine. Its human nature to be a great pretender.
What you have listed as issues may not be issues at all. This may be nothing extraordinary - stuff like this can be a disorder if its over powering.
But if people are saying all those nice things about you, most likely you don't have a 'disorder' and are just painfully, acutely and incurably human.
