Feeling sad

Ok, perhaps I'm just not able to be happy all the time, or a long time. It seems like I'm good in being sad. As I wrote in "die Bürde der Konsequenzen" I always think about anything. What will happen if i do this, what will he think if i say that, what will she think if I wear this. It is really hard. Everytime someone says: just stop thinking, but did you try to stop thinking before?
Time for a test: sit down, breath in and out, close your eyes and think nothing. I can nearly promis the first thing you will do is thinking, about everything.
My head feels so full of thoughts and feelings, I think it has to explode one day. And that day does not seem to be too far away.
At the other side I am really easy to fill with enthusiasm. A friend of mine once said that I am like a little child who sees something new, I can fall head over heals for something or someone. That I fall for someone is not that often, but when I fall I do it with all my heart. I would do -nearly- everything for that someone, just to see him happy. Believe me that is not the way you should fall in love. Because it is a good way to find heartbroken in the end.
Lots of love (especially to the sad and heartbroken), Lena
