First blog

Hello first blogger here,
   I'm starting this blog because of certain things happening in my life I sometimes want to express. One main reason for this blog is that lately I've been really sad and I worry about stupid things and get panicked.  I haven't been able to sleep either. I can't stop it. I was in the shop the other day and there were so many people around me and it was so noisy. I didn't breath and was panicked for no reason. I sometimes think I'm going crazy. If you have any idea what it is or anyway to stop it please comment , I would be grateful if you could.
