problem with in law

Hi everyone I have an issue with my in law. 4 years ago,when my lo was only a few months old, my husband n i had a huge fight. This is regarding my mother in law. Although it was not really her fault but she was partly to blame. The fight was so bad,that i pick up a knife a wanted to kill myself. This fight happen in front of everyone( my husband family only). After that fight,everyone from his side block my call and whatapp messages. My mil helped to take care of my lo during that time, but due to the incident,she refuse to take care of my lo and my husband didnt bother to help in finding an alternative. Eventually (current situation)everything was ok and back to normal except: 1. My mil still block my number. If she need to talk to me,she will call my house phone or my husband. Same goes for me,i will call my fil or their house phone. 2. My sil wont bother to reply to any msg that i send to her. She will only msg me when necessary. She and my mil will give each other looks when i scold my lo in front of them. She has just given birth to her lo and she dont really like it if i were to carry him or play with him. She did not specifically say it but her body language is very obvious. What would u all do? I want to be closer to my in laws but its hard if im being treated this way. Ive tried to do things in their favour,even my husband sees it. But he will only tell me just let them be.
