We all have them, we may not realize it but it's so true. The list of friends that we have go on and on, but which one's should we really consider toxic? I mean, to me, if you're being put down or feeling that you're not being heard, odds are you're friends with a 'toxicologist' who knows what they're doing.

1. Help Me, Help Me

They talk about themselves without letting you have your own voice speak up only if they really need you're guidance. If they have issues, they rely on you to fix it. But Lord forbid, you have an issue, they blank it out and quiet frankly they don't care. Friends likes these see that you're a 'Fixer,' who has the natural tendency to fix issues that may not always concern you- that's not a bad trait, it just means you care, but sometimes a little bit too much.

2. Mr./Mrs. Me

Me. Me. Me. Me- It's all they need in their lives. Generally, it's their way or the highway. It doesn't matter what you think. They only look out for themselves. If it's sports, they're thinking they're better than you. If it's school, they feel the need to silently or loudly make it evident that they're 'book smart' and you're not. Either way, these friends can be helpful but more often than not it feels like they're constantly degrading you because you're not them.

3. TRB (The Resting Bitch)

Basically the Resting Bitch Face has a legit body and personality. It's needless to explain how these friends influence you with their toxic tendencies. But to give you a jest of how they are, they love to gossip about others and they'll be the first to gossip about you once you mess up. But in all ends, they're just a bitch. Often they're favorite saying is: "Sorry, not sorry."

4. Hate Bait

"Oh my gosh! That is so fetch!" If she's the next Regina George, she's the Hate Bait. She'll act like she's you're friend but in the end she'll only use you for a certain favor or to get above you. She loves you but she hates you. Needless to say, she's similar to a TRB.

5. Mr./ Mrs. I Don't Care

She or he will be your right hand girl/guy, but doesn't really care. They only hangout with you if you're bored. You invest and confide in them but once you're MIA the MIA turns into a diminished or non-existent relationship. The moment you see them at their job or out-and-about you'll ask them if they want to hang out but they probably won't text you or hit you up to do anything. Quite frankly, you're on the back burner.

Old or young, male or female, we'll have these five 'toxicologists' in our lives, maybe not all at the same time, but odds are at some point. But when you befriend these people realize what you've signed yourself up for. Just get ready for some silence and lack of positive feelings from them towards you.
