Note that if you live near a university there's a decent chance they have a public-facing clinic as part of their psychology school that charges on a sliding scale
People following you, knocking on your door, speaking Spanish (which I presume you/your ex-employer don't) are both all trademark symptoms and things that a company that fired you is extremely unlikely to do (because why would they?).
Seriously, please go see a shrink. If I'm completely wrong, the cost is pretty low, but if there is something to this, it may change your life.
I will. I'll have to figure out how to do it while abroad, and with funds being tight it might be a challenge, but it should be possible.
Unfortunately, I really am 100% sure it's not the case that it's imaginative--there's too much evidence. I.E. at a company after-party I quipped about something unethical/problematic one enployee who used to bully me (before I first quit) did. He started throwing bottle caps at strangers and pointing at me... Another employee witnessed this.
Some in the company joke about their political and criminal ties. Was about 150 people company and management team of about 25 was all fired... Apparently for this.
They're all sales people with personal connections who got into a company and nearly drove it into the ground before parent company kicked out all of management, but after I got bullied I fought back against some of the worthless underlings that remained. Egos hurt. Careers at stake. Etc.
Anyways while I have no doubt in my mind the company did not explicitly engage in this (it wouldnt serve any benefit to the company); likely the above mentioned person there engaged this in his free time--it wouldnt be hard to drive across town with a bunch of money and offer a job to disenfranchised youths.
While I can personally guarantee it was real, and I will see a psychiatrist anyways, to rule this out... If it was somehow hallucinations, then it all ended when I left anyways, and it never presented associated symptoms in my life. So the problem I am more concerned about is figuring out how to approach employers at this point, establish myself somewhere in the States I wont be homeless (you need proof of income to rent somewhere), and start getting productive again.
Unfortunately, I'm really afraid this does, indeed, all sound crazy, and it only detracts from getting help to solve my problems.
