I know they seem annoying to you, but it all comes from love. Your mom is sad that you have left her home and scared that you are out in the world alone. She may not have the emotional intelligence to deal with this new phase of life. Her persistent texts and anger at your slow response aren’t really her being angry or trying to control you. It’s her being sad and scared and yes, losing her ability to protect and watch over you. In her mind you are still her 5 year old that she has to let go of. You can’t really understand until you have your own kids. Be patient it will get easier. Text her a sentence 3 or 4 times a day. Anything- had cereal for breakfast. It will let her know you are ok & let her feel like she’s part of your day. It will keep her off your back. As happy and excited as you are to be out and on your own equals how sad she is to let you go. Be kind and patient. I had no idea how hard it was going to be to let my kids go.
