Postpartum baby blues or depression?

Today I’m 2 weeks postpartum. A lot has happened in the last month. Diagnosed with pre eclampsia, hospitalized 3 times, had to be induced, had HELLP syndrome, baby was smaller than she was supposed to be and had to stay in the NICU for 10 days and now we’re finally home. I am so overwhelmed, I don’t feel like myself, sometimes I cry, I feel worried sometimes and I’m not sleeping good. I feel like I clinging to familiarity and normalcy from before I had my baby. I don’t know if this is postpartum depression or baby blues. Sometimes I’m fine and other times I cry. I don’t even know what’s wrong. Please give some insight. Are my feelings normal or do I need help?
