How do i stop worrying?

Me and my boyfriend have been together for abt 9 months, coming on 10 months. We r long distance, always has been. we haven’t met each other yet. anyway, recently me and my bf were fighting for like a week or two weeks straight if i remb because of my mood swings. we have found common ground for fighting. we aren’t currently fighting but not talking a lot. it breaks my heart. we r texting a lot and we do have calls. but he is a hard worker, he is constantly on the go with his parents. even doing rosarias for a week straight but it makes me worry/ i am someone who gets anxious abt stuff i can’t control like the future. we even had a fight about that because i like to ask question on what he thinks will happen for us in the future and he said he would rather live in the moment and not have a specific answer. but i am so worried right now. i just feel like idk we talk but it doesn’t feel yk. he is busy and i am not rlly as busy as him. *** it could also be the fact that we aren’t fighting which makes talk feel awkward well not awkward more just idk i feel like we r barely talking. i feel like smth is wrong and we have broken up before for thinking we r better as friends and i had a feeling right now i don’t have that feeling but i’m scared bc maybe i’m right maybe all this overthinking is right and i wanna prepare myself just in case we break up or yk we don’t make time for each other. i am so scared to lose him over this idk what more to do.. i get he is busy and i wanna stop worrying i ask if he still loves me idk maybe i’m clingy we do have independence in our relationship. i wanna make sure that this is the guy for the rest of my life and i’m not making a mistake since i’m 17 and he is 18 ik it’s young but i want it to work out so bad - maybe i feel like this bc we always call in the morning bc of his schooling currently and we haven’t since he is off idk i’m scared what if we r fading away idk how to stop overthinking every message feel like we r fading away i’m so scared i don’t want to lose him he feels like the one he is so sweet and amazing i look up to him as a person maybe he is rlly vague and not good at comforting but idc i want it to work idk i’m panicking rn i am also a catholic i’ve been praying but when i ask for signs it seems like it’s meant to be but sometimes well once it seemed like God didn’t want us together bc we fought and i asked if we could not fight that night if we r meant to be but other night it seems like he listens and makes it clear i do get a sense of peace but worrying idk i just wanna feel calm how do i know we r fading wwwy yk ugh
