i have this problem where i laugh at everything no matter what it is and lately its been troubling me more and more because i used to think it was a defense mechanism for when i feel uncomfortable but now i think its something else and i don't know what to do about it i guess my laughing all the time began when i was 3 or 4 years old and now i cant help but to laugh when i should be serious about the situation at hand, can anyone shed light on this?

im not sure where to put it, if this isn't the right section by all means move it to a more suitable section of the forum :3
