Understanding the 'All In' Introvert

Firstly, let's define the introvert. As per Merriam-Webster, introvert is defined as:

":  to turn inward or in upon itself: as

     a :  to concentrate or direct upon oneself

     b :  to produce psychological introversion in"

Next, let's see what Urban Dictionary says about "All In"...

"Originally and still a poker metaphor, 'all in' has also come to mean a situation whose subject is unreservedly involved, without qualification. Fully committed." 

Now, when you put these two ideas together, they seem to infer that an "all-in introvert" is an oxy-moronic term. Ummm...did I just call myself a moron?? Not even a little bit. What I am calling myself is someone who can devote themselves wholly to a situation, but maybe has a hard time expressing that intent. Nota bene...introverts aren't shy, they are just choosy about whom they share their lives, and hearts, with.
An introvert, such as myself, is someone who abhors small talk (really, just can't do it), enjoys emotional connections with small groups of people (prefers one-on-one situations), and must (I repeat MUST) take time for themselves to recharge after they have spent any time out in the world. Dealing with the bombardment of sound, emotion, and dialogue on a daily basis is draining! Even when we like the people, where we are, and what we are doing, we still need some time to decompress and recharge our depleted, proverbial, batteries.

Now, to the crux of the matter. An introvert is able to be all-in...a state that comes naturally since their nature is to be "there" for people whenever and wherever needed. If it is at all possible, we will drop whatever it is we are doing, and rush to be by your side. If we can't be by your side, we will listen to you, support you, provide a comforting shoulder for you to lean on, and bend our ear to help you deal with whatever ails you at that moment. This is how we express our care and love for you. We may not always be able to say it, but we may be able to write it. So if, in your time of trouble, you get a note from your chosen introvert, accept and appreciate it for what it is - a love note. Our goal is to ease your pain. If we can do that in some small measure, by making you feel loved, heard, safe and comforted, then we will do it. We never know if it will be received as such, so if you feel (in some small place in your hurting heart) that if you have appreciated it, please let us know. We will be forever grateful, and remain staunchly loyal to you.
