Hey Lucami,

I use to have this fear as well,at times I still do. It started out when I was younger where I didn't have much of a choice and had to stay home alone. I feared many things while being home alone and slowly over came this by doing things that kept me occupied so I wouldn't have time to think about my fear. I would listen to music,sing,dance,watch movies,draw,clean ..anything to keep my occupied and time went by faster as well.
I now stay home alone almost every day. I recently became timid again because there was a break in in the neighborhood and I just recently moved here so every little noise I hear I make sure there's nothing wrong and honestly 90% of the time there really isn't anything wrong, our mind tends to play a bit role in making us feel things that aren't there. As I type this, I hear noises..and it's most likely just the neighbor's house,wind, even the fridge makes weird noises. Fear will make the smallest things appear bigger than they are. Sometime we have to take a deep breath and actually believe that everything will be fine. Even chatting with people online made me feel not so alone, believe in yourself and know that you will overcome this. I know it is easier said than done, but I hope you are able to
