hello, I know exactly how you feel, it took me 3 years to find a job I enjoy and sometimes I still don't feel like I am where I should be life, how you are feeling, is how millions feel, so you are not alone, have you thought about going to talk to someone about this? like a job centre that helps support people with their struggles of finding the right job? and as for what you feel in general, many people feel like that, keep strong keep your friends and family close and try to open up more, you will feel better about it, at first it will be hard but be brave and strong! Im here if you ever want to talk ^^
