Missing Writing

I haven't written anything for myself for a long time. A few years ago from now, writing was very important for me. When I was sad or angry, I always used to write my feelings but now I'm not writing my feelings. I know that I need it. However, I don't know what the problem is. So, I can't solve it. Somethings make me stop. If I start to writing, I won't finish it in short time. It will be very long and everything will be inside it. I think I'm scared of what I will write. But, this situation can't continue forever. One day, I will start again and I will feel really better than now. I just need a very little "inspiration".
