Firstly, please don't kill yourself. Hold on. Please.
There are ways for people to legally change their names. I have never looked into it, but I know it exists. You would need to approach the government of the country of which you are a citizen.
About employment, I have never been employed myself, but would you be able to get a casual job in the meantime? They might not do background checks, if it's a very small business or minor role. It probably wouldn't use your education, but at least could provide you with an income. I don't really know what your situation is, so it's a bit hard for me to give advice.
I would think that first priority would be to pursue a name change, because then you will have more freedom. Sorry that I haven't been very helpful.
Good luck!
