Thinking about getting my tubes tied but not sure if Im doing it for the right reasons

I had a meeting with my obgyn to see if I can get my tubes tied Im not sure if I want to be a mom anymore let me give you a little back ground I had a baby at 19 she had cp and was blind I took care of her till she was 4 and I had a suicide attempt and she had to go in to foster care she was adopt a year later because I just couldnt take care of her by myself anymore I cant see my self being a single parnet again and every guy I meet Im good enough to have a baby but not good enough to be a wife I dont feel it is emotionally safe for me to have a child again I delt with so much emotional stuff with my daughter and fighting with the school system I just dont have that fight in me also while I was pregnant people made me feel so bad about being pregnant I will never forget what the paramedic said while in labor and delivery" I would be ashamed if my daughter was pregnant at 19" I still feel the effects of my daughters birth I dont think I can handle it
