hello Sarah. sounds like depression to me but maybe only because of downtrod-deness and not full blown clinical. being w/out a job for a number of yrs can really bring anyone down. it messes w/ their self-worth and brings ego issues. you must do action to overcome those issues.
how do you support yourself? - are you independantly wealthy so you really don't need to find a job? is someone else (parents?) supporting you?
whatever that answer is - you know there are many non-paying jobs that can give you experience and also a way to meet more people. you can do internships - or - i don't know what Sweden has - but US has Peace Corps, Americorp - & there is also Oxfam International. you don't mention any particular interests or what your degree is in - 'Sweden Bear Tracking Volunteer Project' - This program, based in Sanfjallet National Park, is focused on providing volunteers with improved tracking skills and improved wilderness experience overall.
Helping other people - or animals - or other world interests is often a very good step in helping yourself. But you have to make that first step to become involved. Nothing is going to happen if you stay in your bedroom wondering about things.
