My daughter when she was young, i mean four or five, had many anxieties, she needed her buttons done up really tight on her cuffs, her shoes really tight, she worried all the time as she went to school about friends not speaking to her she used to have night terrors, not nightmares, she didn´t wake up when someone tried to comfort her, and she went on to have those and other anxieties into adulthood, obsessive compulsive disorders and similar things, depression etc. I wish we had addressed these things when she was young and had professional help as once she had the help in adulthood she has been much, much better. She is 32, healthy and has two beautiful children, the only time she gets anxious now is when she gets really stressed but recognises it for what it is and has ways of dealing with it. Seek help!
