I came across this topic..because I too am in my third year of college and I HATE my major...a little too late now though. My major is Criminal Justice but after a few internships I realized it is not for me...so I will go for Marriage and Family Therapy as a masters.
Anyhow; reading on how you like pregnancy and the birthing process maybe you should consider being a doula; either as a side job or full time. I went for training for it and it is an awesome experience!!! You can make your own prices. I teamed up with a women's center and helped primarily teenage and single mothers. It's rewarding!! You can either help them through the entire pregnancy and then through the labor...or just labor. You do not do any delivering...you are simply a coach to the women. You help them with meditation and breathing. And are the hand they hold when they can't bear the pain.
Hope this site will help you if you are interested...
