I could be wrong but here is how it seems to me....
I mean this kindly ok?

I think you connect a self bullying habit to "introvert" that is not actually an "introvert thing."
Here are your goals in your post:
- get more comfortable with meeting new people
- let my true personality be seen from the start
Small, doable things. Sounds reasonable so far.
Here is how you talk to yourself in your post:
- I think no one wants to hear anything I have to say
- I think getting my wife was a miracle
- I think no other woman would be interested in me
Why do you put yourself down like that? You are your own bully? Is this a habit?
How does that help you attain your goals? You beat you up before leaving? How is that you showing up in good shape then?
Why discourage self like that?
I think YOU talking down to yourself hurts your confidence and your willingness. Could change this way of talking. Be realistic rather than disparaging when you head out the door. Correct the "popcorn thoughts" that pop up if they are not realistic. You are not your popcorn thoughts. You are the one doing the thinking.
- I think no one wants to hear anything I have to say (I do not know yet who I will meet and talk with today. I have to get there first.)
- I think getting my wife was a miracle(Wife and I continually create a good relationship together.)
- I think no other woman would be interested in me (I do not know at this time if any other woman might be interested in me.)
Once you warm up you say you do fine. So...not actually a problem there in interpersonal relating with others. Liking to socialize in small groups or one-on-one is what introverts do. They are not up for big old hooha things. So you work the size turf you like best and over time meet people. It isn't the introvertedness holding you back.
I think the issue holding you back is how you talk down about you so you do not even get out of the starting gate to the small size gatherings you like best. The INTRApersonal skills.
I am an introvert and I love both my introverted friends and my extroverted friends. I see my extrovert friends one-on-one and skip their big ol' hoohas. I do not talk to myself like you do though. It is not a healthy thing to be doing for your mental health. Putting yourself down lacks self respect
Could monitor how you talk to yourself in your head so you talk more kindly, more respectfully. Then you might become more willing to let your true personality shine more often and more brightly when you are not dinging your own self.
Which could increase your comfort level when meeting new people. Should something deeper emerge from getting out to meet people...great. One thing at a time. You can do this!
