Resistance to prospecting

I find myself self-sabotaging by procrastinating when I think about having to prospect for clients. I hesitate because I don’t want to get yelled at and to feel like I did something wrong. I used to be in real estate sales where I cold called and I got yelled at all the time (people cussed at me). It made me feel crappy and part of me still hasn’t let that go. I think it’s because when I was younger, my parents always yelled at and criticized me when I made a mistake and they made me feel deeply that I did something wrong and that there was something wrong with me.

So from then, I always tried to be perfect and to not make any mistakes so I didn’t have to feel those feelings again. I guess now, even as an adult, I despise getting yelled at and feel really bad when I make a mistake. I somewhat obsess over the mistakes I make by replaying them in my head. Now that I’m in a new business where I need to get clients again, I’m feeling a lot of resistance to prospecting. There’s this irrational fear I’m going to get yelled at. I tried doing the model but I’m not sure what my unintentional thoughts are and what my intentional thoughts should be. How do I do the model for this? How do I get over this resistance to prospecting and putting myself out there?
