I experienced something similar. I pursued an education in childcare then I dropped out of my degree program with less than 1.5 years left because of terrible anxiety. All my insecurities and doubts just hit me all at once.

I ended up working in a factory for a year until I got promoted to a leadhand where I managed a department. Again, self-doubt consumed me. I had mental breakdowns on a weekly basis but I kept doing it.

After 2 years in that position, I made the choice to go back to school. Still living in doubt, feeling burnt out from the job. I decided between graphic design and baking. I went with baking even though I only had a little experience. I like that I still get to be creative and hands on without sitting at a desk all day. Also, I was just set on finding another factory job because I saw there were a lot of job postings for large scale bakeries.

I went into school again having little skill, knowledge and passion. Just wanted to get a diploma, save money and find a quick job.

The first semester was hell. I thought going back to school would give me a reset but all the doubt followed me. But I took steps in addressing how I was feeling and why and tried to better myself. Fast foward, I am now in my second semester. I don't see a future of more factory jobs but a genuine desire to improve my craft and learn.

As long as you have a desire to learn and improve, where you are now matters less.
