Super anxious....

This period has me feeling really bad about myself. Also, my sisters gender reveal party is on Saturday & I invited my boyfriend. He said he’s almost positive he can come unless his job calls him for a job last minute but he doesn’t think that will happen... but I can’t stop stressing about it & I keep telling myself he’s probably not going to come Bc I’m so used to boyfriends letting me down & not giving a shit about this stuff... I literally can’t stop obsessing and worrying over it. And I feel like the clingiest craziest girlfriend. I’m so paranoid he’s going to leave me. I just keep looking through our texting over analyzing everything. I feel like I text him way more & am way more enthusiastic about our relationship. Idk. I just feel like shit & I can’t sleep. Help! 😔😔
