My dad left when I was young which caused me to go though horrible thing like hair loss and depression and years later he comes back and then leaves shortly after. I love my dad but I don't think he wants to be part of my life because hasn't keep any his promises. He has a new wife now and she doesn't know he has kids or he lied to her. He promised to keep in contact with me but I find it hard to text to him because it worsens my depression and I don't know how to tell him how I feel.
