I've never made one of these before, I apologize if its not well organized

I was bullied all throughout middle school and then ignored in high school, my "friend group" wasn't great. I had to ask to hang out every time, none of them offered. I didn't know how to act around girls that I liked. I used to chase girls through the halls and cat call them. I hate how I treated girls in high school. My guidance counselor eventually told me to stop talking to them. so for my junior year I stopped, and then covid hit. it didn't really affect me that much, since I didn't talk to many people, but not having anybody my age to talk to, looking back on it, was a big problem. I was also obese for all of high school

In the last year I've lost 107 lbs and put on muscle. I have a stable decent paying job and own my own vehicle, I'm still living with my parents, but I pay for my food, insurance and gas. all of my family members say that I look great, I think I look good, I also feel great. my problem is I have no experience talking to girls, and every time I see a girl I want to talk to my brain repeats 2 things to me:

don't bother her

you aren't attractive enough

I despise who I was and how I acted in high school. I'm terrified of making women uncomfortable, so I just avoid approaching. I also don't want what little self confidence I've built up get torn down by being rejected

a few months ago my mom got a new coworker named Lindsay. My mom showed a pic of me to Lindsay and she said that I was cute. We've been texting for a while and have a date roughly planned around early may (she's been busy with a pet sitting business). I'm nervous that it won't work out

even with a real woman finding me attractive I still can't make my brain understand it. I hate it.

I don't know what to do, I feel stuck, and I know that every day that passes is another day I'm going to regret
