don't know what to do next.

I started learning web developing in 2017 after the 1-year learning I started freelancing in 2018 and do some small and simple client project. After that, In September 2018 I got my 3rd big project which was an E-commerce website. When I was developing this project I realized that I don't have the proper skills and knowledge to work on such a big project. Due to lack of knowledge/skills, I dropped the project in January 2019. From January I have been thinking about what I should do now. Which options I have now. as you guys can see I invested my 2 years in web developing and I don't know where I'm standing now. I need a mentor who can tell me and guide me about what I should do now. So, Guys, I'm facing a very difficult time now so please please help me if anyone can.

Sorry for grammar mistakes.
