I'm pathetic but

It's the little things that change how I feel.
The tiny thing's people don't even think about, but happens subconsciously.
The reason why it affects me so much is that psychologically, the subconscious acts of others are what truly mean to come out.
They're what people intend.
And every time, I seem to notice something people say or do that they didn't make an effort to on purpose.
And every time it's something that hurts my feelings, it really makes me down.
I realize I sound like a child, but my emotions are stuck there.
I've lived my life in a way to make things very hard to deal with.
Any single thing can take me from happy to depressed.
So ridiculous, but it's true.
And honestly, I'm surprised people deal with it and me.
But I just need to be up front with myself and admit that I have problems.
I pretty much always have.
And it's hard to figure out what to do when I'm always alone.
