I have started to realize that a laugh a lot and in very "not usually laughable" situations.
If someone is having a serious conversation with me, I find it hard not to smile and I get in a lot of trouble for it. I usually end up biting my tongue, covering my mouth, or other things in these situations.
It only started happening now, but when I cry due to stress (more of disappointment in myself, I am a perfectionist) I start crying and start laughing really loudly. Once a teacher starts talking to me, I calm down.
This happened today, but I was watching TV with my mom and she said she was going to move without me and I had to take a shower. She said I could take one in the same time as when the next show started. I was telling her to not go on and don't start without me, when I started laughing wildly, and could only stop when I got to my room. (Not the first time something like this has happened)
I also seem to laugh in situations where I there is an awkward silence or tension sometimes.
Does anyone know why?
