Anyone here an only child with a parent who refuses to let you travel?

To start I am a 31f who lives with my husband in Texas. I moved out from my moms house at age 28 when my husband and I bought a house. I want to travel to many places, but I feel i am a bit slow at times intelligence wise, and I also have anxiety disorder. I’ve been pretty sheltered for most of my life and I’ve always traveled with someone else. I want to go to so many places, but my mom and husband don’t want to spend all that money on travel and don’t have the time off like I do. So my solution is to travel alone. I want to start with a solo trip to Chicago or New York. I would use common sense safety, but I tend not to pay attention to my surroundings, at least this is what I’ve heard from friends and family.

My mom tells me I am selfish for wanting to travel alone because she said I will make her and my husband worry. She also says if I ever book and trip alone and go, she will never speak to me again. My mom and I are very close, more like best friends, she is my only family in the area. I don’t want to miss out on the opportunity to travel, and I don’t want to force anyone to go with me just because. I also would like the chance to grow and face my fears of traveling alone. Any other only child solo travelers or people in general with helicopter parents who solo travel? Any scatterbrains out there who solo travel? How did you start? What did you tell your parents? Any and all advice would be greatly appreciated.

TL DR: I’m a scatterbrain with anxiety who grew up sheltered and not doing much on my own, but want to solo travel. My mom says I’m selfish for wanting to travel alone because it will worry her, but I wanna live my life.
