I don't know how the education system works in your country, but if you really absolutely hate your job and it isn't just an inconviniance, the right step in my opinion is to get an education in another profession (at least in Germany that's financially possible if you really want it).
And I know myself how hard it is to make friends if you have bad social skills and are generally a strange person, but I think you never should stop trying and if you keep failing, look for help or advice.
To be honest, you are a lot older than I am, so I don't have personal experience how it is to be in your situation, but most guys here are in their 20s or even younger, so for them I think it is good advice.
Also I watched your video, holy shit, you seem to have such a lot of deep seated anger in you, I think therapy really is the only way to get out of it. Don't let yourself be discouraged by one asshole who has wronged you. You need to be absolutely open, honest and willing to engage though when you go to therapy or it can not work
