Is it normal to feel super duper emotional after birth?

Since giving birth on April 1st I have been so emotional. Everything makes me cry. My mother in law keeps asking me if I have postpartum depression and I don’t think I do but idk why I keep crying. Some times they’re happy tears and sometimes it’s because I’m sad. Small things that normally wouldn’t make me sad or cry makes me cry now. Like a girl I went to school with said she thought my baby was ugly and I cried so hard for over an hour. I just don’t know if this is normal or not and I feel like I’m going crazy
