What's wrong with me?!!

So,
I just finished my 1st semester of nursing school and to say the least it was a semester filled with many emotions. One minute I was up, the next I was down. Then I became anxious, couldn't concentrate and then I felt depressed like no one in my household understood what I was going through. I have 6 yr. Old Twin girls so, in my mind I should be able to handle any and everything and I could until Nursing School! Many of my classmates are on different meds ranging from Prozac to Adderall. Im finally.going to the doctor and going to ask her to "fix" me with whatever medicine possible. However, I've been researching and I haven't found anything that is a combo drug that could help me with Anxiety and my Moods. Do any of you professionals have any suggestions? I like to go to the Drs prepared with a lists of things to ask lol.

Family History- my younger sister was diagnosed bi-polar in high school. She's a senior in college and still taking everything from Lithium to Adderall. I just fear I will end up on a ton of meds like her so I haven't talked to anyone about my feelings.
