Thank you for the invitation girl. To be honest, I dont really know my answer for this question. I used to like being alone when I am not in a good mood, same as you I dont want my mood affect others. However since living with my partner, he has helped me to realise an easy way to overcome it. He will ask why and what make me feel sad, then we valuate together if it is worth being in the sad mood. I think this works for me and eventually become a habit. Not only to handle my bad mood, but also other thinks like anger, anxiety...

This week I am quite busy so will see if I can put my thought together in a post. Good luck with the contest :)
