Snail on my sleeve

Disclaimer: Before anyone thinks I'm talking about them, don't worry; I'm not. It's all about me. Me me me. XD

So, I have a problem.
This problem has been around since I've been born:

I wear my heart on my sleeve and I easily fall in love.

I do. It's all or nothing for me. I either care about someone/something or I don't. And if I'm inbetween, it's just because I haven't made up my mind yet.
And I don't just mean with people; I mean with animals and inanimate objects.

Example:
There was a snail on the side of my apartment the other day. I cooed at it and waved as I went to work, thinking that snails are slow and I'll see it when I'm on my lunch break.
When I came back on my lunch break, I found it crushed. It had worked its way to the ground and had been stepped on.
I was so sad.

Is this normal?

And this leads to even more problems than crying over crushed molluscans; it leads to me getting in my own way.

If I'm giving 110 percent, for some silly reason, I expect it in return. Be it friendship/relationship/coworker....ship.
Then, when the 110 percent isn't given back, I'm incredibly disappointed.
I set myself up for the fall!

Why?!
Why do I continue to do this to myself?!
Why do I think that someone is going to be on the exact wavelength?

It's not really purposeful..... it's pretty much automatic with me.

Watch out! Rage ahead

Felt like someone had slipped some rage pills in with my water yesterday.

The monster amount of nagging and questions were weighing on me and, I kid you not, at one point the thought: "if someone asks me to do one more asinine thing, I'm going to stab them in the face with my cup," ran through my head.

Worry not fair readers, I would never do such a thing. I'm not prone to acts of violence.
I stopped being pissy after a short while and went back to being sweet, bitter, accommodating Rose.

P.S. don't piss off the snails
