Frustrated vent.

** edited to make it clear**

I’m 19. I have a 3 year old and a 2 year old that I adopted this year. I am new to being a parent. I took it upon myself to adopt them when my fiancé’s ex girlfriend, the mother of them, abandoned both the 2 year old and 3 year old. We got our foster license to take the 3 year old as my fiancé is not her father, and now we have them both.

Long story short, I get so frustrated. Sometimes I start to yell and have to pull myself away because I absolutely hate yelling, but they fight so much because they’re so close in age.

I feel like a horrible parent. Both girls call me mom, and I just feel like I’m going crazy sometimes. I have no friends, and no help as my fiancé works all week, and sometimes even weekends. I’m with both kids all week from 1:30pm to 10:30 pm, and some days 9am to 10:30pm.

I just want to cry. Any encouraging words would be nice.
