What else, besides alcohol, reduces social anxiety?

I cannot say that my life is going downhill, but it is not getting any better also. Steady job with payment that is just enough to live through the month, bunch of no good friends and everlasting fear that tomorrow brings nothing that is my life. I have developed fear of getting out, except for the job and I have been starting drinking last year, and now I cannot do anything at home and be calmed if I don't drink something. Anything. What else, besides alcohol reduces social anxiety?

It seems to me that you might be having serious depression problems, and that cannot be cured with alcohol, you will only make things worse. I suggest you to get some professional help, some expert to talk about your problems with. It might sound prematurely, but is it really? Of course, there are also medications that could deal with your condition, but first it has to be determined if you are suffering from any condition at all. That is what experts are for. Don't be embarrassed to ask for help. Help yourself, please. And try to stop with alcohol.
