I don't hang out with my friends too often, but when we make plans I'm always excited for them. But when we end up meeting, I feel so exhausted in no time at all. 

I always instinctively act different around them, I become louder and more energetic, but when I'm alone I don't feel that way at all. Then I just feel tired and want to go home not long after meeting them.

Does anyone else get this too? The exhausted feeling after putting on an "act" around others. Because at this point I don't consciously act differently around them anymore. It's become second nature, because if I act normally around them I always feel guilty for ruining the mood as I'm just naturally gloomy and don't really smile or laugh often.
