Pallando, you gotta stop reading articles and incessantly looking for reassurance.
Every time you run with an anxious thought and then act on it with a certain behavior or compulsion you're strengthening those neural pathways, reinforcing to your brain that this shit is worth worrying about (it isn't

).
Try not to stress when you get a thought in your head that bothers you. Generating thousands of thoughts a day with little quality control is what you're brain does -- you're fucking up if you attach meaning to every little thing you think.
Meditation/mindfulness might be worth looking into. People who aren't as neurotic, people without anxiety disorders like OCD, they might still have the same thoughts as you but they can let them go more easily.
So start challenging some of your thoughts, and be mindful whether your actions are actually helping you or if you're just rationalizing some bullshit under the guise of self-help.
I promise you the better you get with all this the more natural dating (and life) will feel. Just gotta get you out of your head, less inhibited, and more comfortable being in the moment thinking on your feet.
