My boyfriend's been on vacation for the past week and I was okay the first few days... But then the depression came. He comes back tomorrow night and I'm excited but this week has been AWFUL. I don't know what the hell is wrong with me. I don't have any IRL friends and the friends I have online I barely speak to anymore. For some reason, ever since I've started dating again, I've just neglected the friends I do have and I know I'm doing it but I just don't care enough about them. BUT ANYWAY, the worst were the constant, constant, CONSTANT thoughts of my boyfriend suddenly not liking me anymore or breaking up with me as soon as he comes back, even though we had a conversation literally the day before he left that he thought something was wrong with me and I wasn't as interested anymore. And he frankly told me if anything like that happened with him, he'd talk to me about it first before even considering breaking up. 

I've been overthinking EVERY little thing. Even though he tends to text back slower than me, I got over that pretty quickly but it still bothers me. I just don't bring it up because I don't want to seem clingy. He sent me a random text that said, "The men's bathroom." He was actually trying to send me a picture of the bathroom but my stupid, freaky ass thought he was sending a text to some girl and he was cheating on me in the men's bathroom. WHY. WHY AM I LIKE THIS. WHAT PERMITTED ME TO BE LIKE THIS. I have high self-confidence when it comes to my looks (i.e., I can look at myself in the mirror and like what I see) but when it comes to emotionally, dear jesus christ... I am a mess. My boyfriend was cheated on and has given me no reason to distrust him. I know there are many things that he likes about me and not one thing he dislikes, yet I'm like this still. It freaked me out for hours until he finally texted me the picture. Does anyone else relate? If you do, teach me how to stop being crazy. 

TLDR; Basically, how the fuck do I be normal? How do I stop thinking that people will leave me when their behavior or a routine they have with me even slightly changes? How do I stop overthinking over every little fucking thing a person does?
