Am I overreacting?

Hey girls, so basically I’ve known my close friend for around 8 years now. We’ve grown up together and ive been there for her through some of the worse times in her life even though I’ve been through shit too I always keep stuff to myself to avoid triggering her. I’m known as the tough friend, uno the one with no problems..the one you can rant too and tbf I am and I have no issue helping anyone regardless of how close we are. But these past 4 years have been my lowest and it’s really taken a toll on my health. It’s weird because not one person noticed anything even my close friend. Anyways, she’s been doing much better these past few years and I’m so unbelievably happy for her, she found a guy she’s obsessed with. But that’s just it... she’s completely obsessed with him. I live about 20 mins from her and he lives maybe 1/2 hours away yet I never see her anymore. She has uni a few days a week and will leave to see him Friday and come back Sunday night. Yet if I ask to see her or try to make plans to meet up it’s always, “sorry I’m with my boyfriend” or “sorry I’m tired from uni”. Erm..I have uni yet I have no issue coming to her when she needs me. Last week I went over to hers to just chill and I really needed someone because I wasn’t feeling great and the whole day and the following morning (I stayed over) she was either talking about how amazing her boyfriend is or she’d be on the phone with him. It made me feel like shit honestly. We were supposed to go out the following morning for brunch and I couldn’t take another hour of her talking about her boyfriend so I left. I know I shouldn’t rely on anyone but I feel like I’ve been there for her for years, and all I was asking for was a day to catch up with my closest friend and forget about my shitty life.

Sorry this is so long
