LDR PROBLEMS?

so basically im in a relationship with someone for over a month now and we always see eachother bcs of school. but since its the holidays now, hes like 7 hours away from me so yeah... its ldr. I've never been in a real relationship bfr and my past one is hurtful. hes literally the first person to actually show the effort in this relationship and i like that. i cant believe i feel for him and he kept saying the same thing but this week is very... distant. very different from the first few days of the week. he says hes with his friends a lot and i dont mind that but hes becoming more dry? its worrying me a lot bcs he said the other day hes going through some shit and when i asked what's wrong he said it was too private to tell me but not too private to tell his friends... yeah it hurts but i cant do anything tho, they're his friends.. and slowly hes effort is going away? hes becoming dry lately and i can actually see him playing valo or any games from discord. i know hes busy with that and i know hes playing with his friends but yk... when i chat him or anything... he still replies but its not the same as it used to be. its very very dry and i hate it. idk maybe im just overreacting and overthinking. i do tht a lot actually. but still... im just scared that he is slowly losing interest...

to anyone whos reading this... pls some advice?
