I (21M) was good in school, academics and making friends anywhere. Then covid hits and after many failed risks in academics ,now my personality is very much conservative, closed and aloof. I had read this pua bullshit and I am more fucked up as I am stuck in paradox of choices and their fucking techniques,scripts. Who tf writes techniques scripts for social behaviours.

Earlier i used to have fun, make friends everywhere. But now I fear friendzone, i fear that i will look like clown,I was more expressive then but now I dont talk that much (be mysterious- pua bullshit)and dont share any emotions.I have fucked up my 3 years of college now my college is ended and i am feeling regret that i missed a lot of chances in making good social life. Many women initiate conversations with me but to be honest i really fucked up.

How can i improve from now and how i stop feeling regret that i should have taken more chances in college socially? And will this regret be forever with me?
