Despise your job? Look for and work towards alternatives that might give you a sense of purpose or is more enjoyable.
Have a bad social life? Try to engage in conversation at work, actively look for places to socialize.
If those fail you or are impossible to change as of yet for some reason you might want to try out different kinds of therapy.
Psilocybin and other forms of therapy are still emerging but the evidence for it seems incredibly strong in treating even therapy-resistant severe depression.
Definitely experience nature regularly, too and avoid living in monotonous, unkempt city blocks.
