Did I do the right thing?

I have a so called friend who only calls when she needs something. A few days ago she called me with another one of her "problems" and I got so sick of it that I told her I'm pregnant and don't need your stress. I also told her to go find someone else to use cause I'm not dealing with it and I told her to get out of my life because she's so negative. I then hung up and she has been calling nonstop stop and I been ignoring it. I been dealing with this for years and I had enough. I'm 19 weeks pregnant with my second son. My other son and my daughter don't like her and they even yelled at her before. I just wanna enjoy my pregnancy, spend time with the kids and have a good life. Did I do the right thing? I felt I was mean but I also know that I think I did the right thing but still feel guilty. So did I handle it the right way
