Help . Need advice

Hello . I got pregnant at 17 by my first boyfriend and then he broke up with me . My entire experience was absolutely traumatizing and just awful . I struggle with anxiety and depression and ptsd already on my own and everything has been amplified since . I love her . A part of me knows that , but Having a constant reminder of all that pain and trauma is so hard . And I’m 20 years old , my life is falling apart as it is and idk if I’m okay mentally to be a mother . she’s 2 and idk what to do .
