Family not supportive AT ALL idk what to do

Sierra
I'm having issues with my family supporting my decision to go through with my pregnancy. I am a 23 year old woman & this is my second child. I have a 5 year old son that is my pride & joy. I work, go to school, have my own home, car, the whole 9. But my family does not approve of my pregnancy. My 5 year old primarily lives with my mother because the school near her house offers occupational thererapy. My son has low muscle tone so that's why he needs it. I go to my mothers house frequently to spend time with my son & on weekends he comes home. Last night I stayed at my mothers house & my grandmother recently moved in with my mom. My grandma is 68 years old. She is NOT HAPPY AT ALL! She woke me up out of my sleep at 6:00 this morning telling me how stupid I am, she doesn't want me around, & she's not helping to care for a new baby. I never asked her too! I feel myself falling into a depression. I am a great mother. I work hard & I go to school for software engineering! I have major goals I'm trying to accomplish. I don't understand it. Family will surely cut you the deepest & it hurts.
