Is this my calling?

I can't sleep. I'm up and I am sad. I have been in a place for the last couple of months of being really unsure that I am in the profession that I was called to be in. In college, when I choose social work, I did so because I felt that it was the profession that would allow me to do what I was called to do. Now, I am not so sure. This is my second social work job and I am beginning to feel the way I did during the end of the last one. I don't feel like what I am doing is making an impact. That sounds egotistical I'm sure, but it isn't meant to. I'm not in this profession because I want applause or even really expect a thank you. But, I do hope that I can say that what I am doing is leaving people better off than they were before we started working together. Right now, I feel like I am juggling schedules, legalities, personality types, and the like without really improving the lives of the kids I serve. I spend all my time making sure the t's are crossed and the i's are dotted, until I have no quality time with the kids to impact them in a positive way. I am worried that at 25 I am already getting burned out in this field. Please, pray for me that God will direct my path and help me to determine what His will is for my professional development.
