if your worries are enough that you can't do a job interview, you should see a therapist. there are people who go and pay a ton of money with far less problems then what you're having. posting this thread was not a mistake. you are worthy of a job, it make take some work to get there but you can do it.

It would definitely be helpful for a therapist to see this post, or if you keep any other writings. it can be a quick way to get a sense of what your thought processes are. I hope you do seek a therapist and improve.
