Well, last night I have the same problems...
Even if I go to bed at 4 am(like always) I was having a problem with my sleeping. I need it like 20 to 30 min to fall a sleep. Sometimes long conversations with you friends can really make you feel exhausted. Last night I was at my friend house and we was talking about his problem with girls. The conversation goes so deep that I start to feel nervous.
After I start to analyzing him and his actions he realize that I was right. Most of the people have problems when you start to tell them the truth. This type of people have an ego complex and they have problems when they want to change them self. I told him that he have problems with his fears, emotions, self-confidence. This 3 symptoms are sing that you are having a problem with your ego. Also, I told him that he have problem to love the others, speaking the truth, low level of intuition and the most important thing... to let go the things.
The first time when start to master this 7 things, then be sure that you already find yourself!
