I have to agree with Mellors.
You can totally do this, Obsids!
Expect setbacks and obstacles. Just think of them of hurdles of learning. You master them and move on to other hurdles.
The lady in traffic was probably having a really, really bad day or something. Unfortunate that you had to become apart of it.

Don't let her negative energies bring you down.

The Target store anxiety attack was probably left over nerves from the job interview not going the way you wanted it to.
It's okay, though, live and learn!

If a job is what you really want then you're going to have to put yourself out there and fight for it.
Don't wimp out! Come on! Pick up the phone and schedule another interview at another place.
After awhile these interviews will be a piece of cake.

It'll get better!
