In fact, you should ask yourself whether you really like this industry. Stick to it if you like, because design pays attention to personal thinking and creativity. You just start from the bottom, and the construction site is one of your favorite places. There are experts working there, and everything is priceless to novices. Be modest, be motivated and be eager to learn. You should put your mind right.
If you don't like it, then find your own hobbies. Also, why did you choose this business in the first place and why did you leave it now? Is it because you really don't like it or because you can't stand being angry for a while? Only you know ~!
These are not experiences, but personal psychological problems. Don't worry. Let yourself calm down and think about it. Think it over.
