Hello and welcome to Healthcare magic. Difficulty in getting sleep is a common condition which is not a serious psychiatric condition as you fear of. Crying is a normal emotional response and if it is excessive and affecting your routine regularly you may need clinical attention. I would recommend you to see a qualified psychiatrist who will spend time with you and help you in making a professional diagnosis. Probably all what you will need is a small counseling, sleep hygiene and relaxation techniques. Hope I have answered your queries. Feel free to write if you need further clarifications. Get well soon.
