People cry not because they're weak but because they've been strong for too long.
Being alone should not be feared, as long as you are comfortable in your own company. A social life is important for good health and happiness but too many people are so afraid of being alone that they are willing to put up with a loveless relationship or even abuse just to have someone there. You have to be happy with yourself before you can have a healthy relationship, and at times that may mean being alone.
