I don't feel emotions often, I just am. I'm in the military so I'm away from family and friends they'll tell me that they miss me or that they love me and I give the standard reply but it's just empty been like that my whole life, any feelings I have go away quickly into a black hole it seems, I don't enjoy things anymore I have no motivation, the only thing I have is the constant thoughts of death, dying, and anything that would harm me I wouldn't do anything to hurt my self or others. I think I care about people but I feel like I see the world differently than others, I do sometimes experience a paranoia I guess where it seems like people are following me when they're behind me or I'm being watched, so I look at what environment I'm in like I need to find the "escape route". I have no energy, I just exist you could say.
If you have questions please ask 
If you have any similar experiences maybe we can talk, but I'm bad at conversation.
