So sorry to hear that your mom is gone. I know what you are going through. It was the hardest for me the first few weeks when my mom passed away which is 10 1/2 months ago. I also felt like I had a hard time breathing. Just remember she is in a better place and she will always love you. Just cry as much as you want, get it all out with spouse, friend, or family. I believe finding other people who have what you experienced helps. You are not alone. I didn't think my world could go on without my mom. I also tell my children often how much my mom loves them and will not be forgotten. I still cry here and Hope that helps you cope with your loss.
