Powerful social anxiety and dating during reboot.

I think you are confusing the cause-effect relationship in here, and I am talking with notion, I suffered and still suffer sometimes for social anxiety.
Porn helped to cause social anxiety, but leaving porn will not cause its disappearing.
Many factors were in this game.
You need to fight them all, and to keep trying, step by step to conquer again your "normality".
Leaving porn is fundamental and really useful, but don't think that reaching 224742 days will just give you alone the confidence to do everything.
It will help a lot, but it's up to you.
What I am suggesting is to take it as an exercise of improving like for streaks.
You abstain for 77, this time your goal is 78 at least am I right?
So if by now you can go to place but feel uncomfortable even to sit near to her(Idk just making an example), next time you will casually sit next to one until you will be ok with that, next time you will just two three sentences, like "hey I am xxxxxx and you?" then you leave, just met her, stop it.
And then again and again and again.
In everything, even in sports, maybe you are a bit afraid in your team to talk in front of everyone, next time do it.
Build your confidence.
And leave porn of course, just don't believe it can be enough.
You have to work.
From nothing it cames nothing
