Crazy emotions 1 year PP

I feel like ever since I had my baby I have had huge emotional changes, hormones maybe? Sometimes I cry for no reason. I used to be able to control my emotions well but now little things set me off. Like before, if I was upset, I could take a breath and get over it but now any little thing sends me into tears. I could be watching tv and something happy happens and I cry, something sad happens and I cry. I also have a weird anxiety about potential bad things that could happen to my child. Like when someone tailgates me when I’m driving I start to imagine them crashing into us and just seeing the terrible imaginary scene unfold in my head. I haven’t reached out for help because I don’t feel depressed, I just feel like my emotions are out of control. Any one else experience this? What did you do?
