You shouldn't spend all of your free time wondering what your boyfriend meant last week when he commented on your haircut. You shouldn't stare at your crush's newest Instagram pic and wonder who the girl he's holding onto is. It might just be his sister, so don't stress yourself out by thinking too much into small things that really don't matter.

If you watch his every move and examine it closely, you're going to start seeing problems that don't even exist. When he smiles at the waitress, you'll wonder if they're having an affair behind your back, when he's really just being polite to the staff to look good in front of you.

If you reread your crush's text ten times and rewrite your response twenty times, the conversation is going to get stale. Not only will he wonder what's taking you so long to respond, but writing out your message over and over will make it sound robotic. If you want the conversation to flow naturally, just stick to saying the first thing that pops into your head, like you would during a face-to-face conversation.

The most common cause of overthinking things is a lack of confidence. You'll wonder why your boyfriend is taking so long to text you, because you're worried he's out with another girl. You'll wonder why your crush called you cute instead of beautiful, because you're insecure about your looks. Overthinking will only make your insecurities worse, so try your best to avoid doing it.

Don't assume your boyfriend wants to break up with you, because he didn't invite you out with his friends. Maybe he assumed you were busy. Maybe his friends aren't any fun and he doesn't want you to be put through a boring night. If you're worried, talk to him. Don't assume a breakup is on the horizon or you could be the one to wreck the relationship.

If you interrogate your boyfriend over something silly, like why he put a certain emoji next to your name in his phone, he's not going to be pleased. If you accuse him of enough ridiculous things, he won't want to be in a relationship at all. That's why you need to take a step back and ask yourself if the thing you're overthinking is really worth all the trouble.

Overthinking can take up a whole lot of your time. Instead of getting your paperwork done, you'll be busy thinking about the last text you received. Instead of sleeping, you'll be worried about your date the next day. When that happens, you're just going to end up unhappy.

The more you think about something, the more you'll stress yourself out. Do you tend to overthink the little things in life?
