I have Struggled With Bi-polar Disorder My Entire Life

I have struggled with Bi-polar disorder my entire life. I was not diagnosed until 6 years ago. Even on medications, the depression is crippling. Sometimes I cannot see past the next second, let alone, the next day. Quality of life sucks. I cannot keep a job. My relationships suffer greatly, and I just do not want to do life anymore. The only reason I keep going is because of my daughter. She is an adult but is special needs. She lost her father 7 years ago and it was devastating to her. Her and I are so close I am her world, and she is my world. If she lost me to suicide, I do not think she could ever recover. Therefore, I continue to live but I do not know how to keep going.
