what am I scared of....

so at the end of this fall semester, I will be considered at college graduate. i'll have a degree in sociology-human resources, but now that i'm almost finished i don't know if this is what i want to be doing. i always imagined working with people, first being a doctor, then a ceo, and now human resources, but the more i look at my life and what i want to be doing...i think i should have chosen a different route. see, i'm really interested in social work with children who are in foster care or orphanages. yes, this lacks money, is an extemely sad career, and could possibly be more than just a little stressful, but just thinking about it i can feel the satisfaction i would get out of such a position.

and i'm scared. i'm scared that by taking on this career, i may not be able to help any of these children, or i may find myself getting attached which will only make the career harder on me. i think it would be worth it though...seeing one child find a family that will love them and take care of them. every child should have that. i just want the joy of being able to help someone have a better life, and i don't see this happening with the degree i have now...

but not only do i have my future career choice to be scared of, i also have concern over paying tuition to continue school...i'd have to go back to get a master's in social work, which would be not big deal if i didn't already owe $30,000 in student loans. i would have to be able to afford another 2-3 years in school, and i don't know how soon i would be able to do it...
