Advise on a Communication problem

so the situation for me right now is.. after 2 years.. finally i have confessed to my closest bff that i have feelings for her...

now she is confused but ive been waiting for her answer.. anyway it goes. ..

but the communication between us.. is getting weird.. like when we talk over the phone she gets irritated..

(have to talk over the phone for a month or so cause we are apart as of now.. she is on a diffrent city)

she has a whole day job and we can only talk at night.. before she sleeps but that talks are getting irritating to her cause she wants to sleep and she says.. i take too long to talk.. i mean i talk slow..

i think the problem is.. i put so much anticipation or like dramatic pauses between sentences or anything i want to say.. it is seen like i am just slowly talking but actully i have so much in my mind i have to like properly set the context to tell her the ultimate thing.. idk even if i am even getting this..

but like last night i wanted to tell her that i am getting little hurt or like sad cause she also cant talk fully about her day to me... like with proper frustration and feelings.. i only just get the jist of it which makes me a little anxious cause i dont get what mood or vibe she is in..

so i started to talk to her about the old days... when we used to talk and then after putting that on context i wanted to tell her that this is the feeling i am having and its okay cause you have work and stuff but i want to just say this..

but it took too long to get there.. she got irritated.. maybe i am beating around the bush for soo long? but then how would i explain her that its okay at this situation.. i just want to tell you this..

so how the fuck do i communicate properly and to the point that it doesnt go far and still i could say what i want to say...
