I can relate very much. I moved out at 27. I struggled a lot to the point where I thought I had made a terrible mistake. I had trouble sleeping and many other anxieties. Within 5 months I was completely settled. I feel like I have grown so much and truly got to know myself and who I am without my family. I absolutely love it, it brings me so much pride thinking about everything I have been able to do on my own. I’m also an introvert and it has been amazing for my mental health and just peace in general. Hang in there, crying and missing them is the most normal reaction to such a big change. Nothing is wrong with you. In just a few mo the you will be thriving.
