Birth mom

Me and my birth mom reunited when I was a senior in high school. I have lived with my adoptive mom, the one I consider mom since I was two years old. Ever since I have reunited with her I have had to change my number numerous times, the weird thing is that she always finds a way to get my number again and it is very annoying because I told her I do not want anything to do with her, becaus of the p rain she is (long story). Is the next step filing for a restraining order? I have logged and taken pictures of each and every time she has tried to contact me. Last time I told her to stop she threatened that she is going to take me back even though her rights were taken away and I will be 22 in a week. Advice please and thank you!
