Feeling alone..

Im 23 years old And I found out I was pregnant 5 days ago. This is my first pregnancy. I was and still am shocked.. I think I've thought of every possible outcome to every scenario and I'm so emotional about everything. I'm starting nursing school at the end of August and part of me feels like I can do both school and be a mom, but part of me feels like I can't.. My boyfriend and I talked about everything a lot the last few days and both decided it's for the best if we terminated the pregnancy.. But I feel so guilty, scared and depressed.. I don't think I can bring myself to go through with the procedure.. Did anyone else have these feelings? Did it get better?
