Do I need help ?

Hey yall, so Im 9 months in since having a csection. To sum this up I get angry when my child cries, to the point where I just wanna walk away and never come back but I also love her to death and wanna hug her super tight. I was on medicine for bipolar anxiety and depression but stopped bc they thought I didnt need it anymore. I also cry out of random, and when I get mad I get horrible headaches and wanna punch the closest thing to me. Ive never been violent but this wasnt a huge issue until about 5 months PP. Idk, is it just my mental health, like do I need therapy, or my meds again??
