I don't agree with all you say but you do write well. And I don't read to be agreed with; I read to learn the errors of my way. There are many many writer groups and they are cheap to join. The trick to writing is to write, which you clearly do. The second trick to writing is to quit caring what others think; if you write to speak truth to yourself, others will read it. The previous post did not sound like sarcasm to me, so you may have a little self-confidence problem. A writer's group will help you with that. They can also teach you how to market your product ... but real writers write because they must, not for the external rewards. You were not being overly melodramatic; you were speaking truth. Others can like it or not, but they can't tell you that you are "wrong."

Your clear strength (as I see it) is that you think in nerd but don't need a translator to be able to speak to civilians. That is a gift. It would serve you well if you opened a small computer store. It will serve you well if you choose to write.

Go get 'em.
