been down n out

lately i've been feeling a lot of ups and downs as far as emotions go. one minute i'll be sittin there enjoying watchin tv with jason, the next minute i don't want to even be around him and i'm not satisfied doing anything i normally like doing. seems like every few years i go through this....depression. how do you explain to someone who's never felt like this that sometimes i feel sad for no reason? that sometimes i feel like crying just because. that even though it seems like all the pieces of my life are falling into place, i can't shake this feeling that it's not good enough. i totally sound pathetic. thing is, i don't know how to fix this. i can figure out how to fix my money problems, or how to take care of myself when i'm sick or how to fix my truck when it's broke down. but i can't fix this. i should be so happy right now, planning my wedding to the man i love. for whatever reason, i'm not.
