I have a new social anxiety and now my life is drastically imploding

Advice will be loved and appreciated.

For about a year now I have adopted a new type of social anxiety that is killing me from the inside. Almost as if my guilts, bad habits and everything else bad about me have planned a coup to overthrow my personality with a deadly form of anxiety! Lately being part of NoFap has been fantastic and has gone very well for me which I am very appreciative for those who have responded to my threads. It has really helped.

But, through the times of my journey to this magnificent and newly founded self-confidence, I have also created a new sense of worry that approached me randomly. A sense of creepiness whenever I walk through my area, I make it bigger than it seems but none the less it is following me wherever I go. I either look around the room or see someone I am attracted to, and in my mind I instantly think ‘am I being creepy?’, then I begin to wonder if I am looking as if I am creepy and etcetera... this escalates to me then seeing someone I may like, and trying to build up the courage to speak to them but end up waiting around until I think a ‘right time’ is soon.

And today made things worse. While walking through a drug store I saw a woman. My eyes had to double check if she truly existed, she was so beautiful, so I turned around and thought I might go upstairs to which she actually walked in front of me. When I was going to the vitamins section she was far away so I was in my zone checking which one to get and I chose one, she came over to the line and I went over there too-after a couple minutes. While I was trying to build up the courage to speak to her I was turning red, and hot, I was stunned by her until I noticed that she was I think getting nervous. Anyway getting to it, when I was going to talk to her she hurried over to the till and I simply looked her direction and she was so so nervous... then poooff!! She’s gone as if she were being chased. I felt so creepy, I didn’t know if it was me or what but that ruined me, and I am now here explaining this to all of you seeking for help and guidance in what I can do to stop this anxiety trip.

I notice her from before when I used to go to the nearby gym, and funny enough I remember seeing her at the post office one day early this year. She was staring at me for a long while-being next to me, and when I looked she glimpsed away, when I moved she stared again and glimpsed away again. I do remember her from that day which was a while ago, but still, why do I feel like a creep even though I am not. What is wrong with me?
