First of all, you haven't ruined your life. There are far, far worse things you could do to ruin your life than get the wrong degree. I'm not sure how it is in Sweden, but here (I'm in the US), it's actually really common (my opinion) for people to end up working in a field that is totally unrelated to their college degree. I know this isn't likely possible for psychology, but in many careers, the degree opens up doors and shows that you can learn and perform, and people parlay that (all the time!) into different fields. Really.

Examples? I work in User Experience. I actually have a graduate degree in this. It's a combination of computer science, design, and psychology (the program I studied in involves all 3 departments.) In my work group, I work with someone who is a former architect. I'm still not sure how he managed to make that leap! But, he did. And I don't think he went back to school at all for it.

(Edit to add: I don't want to accidentally identify myself by providing too many close examples, but I remember - a few years back - I worked with a project manager at a very technical company who had been a music major, and used to work as a radio DJ!)

People get a degree when they're young, then spend the rest of their life figuring out what they like and what they're good at. Some people luck out and figure it out early, but a whole lot of people don't.

It's OK.

So, next question. Is money really the only thing standing in your way? Have you looked into scholarships to pay for school? Work-study programs? Student loans? Teaching internships? Jobs that let you work a late night shift so that you can attend classes during the day (since you said you can't take evening classes in your country)? Have you looked into going to another country where you CAN take evening classes, or might be able to do something to help pay the way (I don't what opportunities are available to you - but here, for example, I know people will go to other countries and teach English, as a way to travel while making some money to live off of.)

My sister got a law degree (as an older returning student) while working a full-time, overnight shift, and supporting a non-working boyfriend that lived with her. People do stuff like this. It is not impossible. When you want something - you find a way to get it. Everyone has obstacles. It just sounds like you've decided it's impossible, so that's it, you're not willing to actually try to find a solution.

One of the best pieces of advice I heard is that... if you want something, you have to go get it. You can't just hope it will happen for you, because life doesn't work that way. You have to find a way to MAKE IT HAPPEN.

Good luck. Don't give up!
