It's not annoyance, and I didn't intend it to come out like that, so I apologize if it did. I'm just trying to stress that it seems to me that you have already in your mind decided that you would prefer psychology, and you just want confirmation that your choice is correct so you can go ahead with it. Correct me if I'm wrong there. I've been there too, and really, all I can say is that you may or may not make a good living with psychology, and it's hard to comment on job prospects. You won't starve on the street with a psychology degree, but there's no guarantee you'll make a lot of money. There's also no guarantee you'll live a comfortable life with an IT degree. I don't think anyone can comment on which one you'd be more successful at, but if you hate IT, and I mean truly can't imagine working in IT for 30-40 years, then no amount of money will make the job more interesting.*
Also, you ask if a psychology degree will get you somewhere, and my response to that would be: where do you want to go?
You have to evaluate where you are in life--what kind of job you want, what kind of job you're willing to work for, how comfortably you want to live, how difficult would a major switch be at this point in your college career, etc. Then you just have to pick. And I'll be honest--switching is always the more exciting option. If you've got a nagging feeling to switch and you do, it's a whole new adventure. If you don't, you end up wondering what you missed out on. I had the same feeling. I decided not to switch. I'm happy with my decision, but it was a personal decision, and you've got to force yourself to sit down and make it.
I repeat--in some fields, the unemployment rates are quite high. This is always subject to change based on the economy, the demand for those jobs, etc. However, if you are in America, you will not starve. Build up marketable skills in whatever major you pick, because no degree guarantees a job.
*okay, maybe a few million a year, but with that kind of money, you wouldn't need to work 30-40 years, now would you?
*hands obligatory grain of salt since this post is coming from an undergraduate*
Also, do always maintain hobbies that you enjoy outside of work and school. If you're overtly stressed out, it can help to have a hobby--particularly one you can find other people to participate in.
