I feel god awful

I don't know. I had this friend who I really liked to hang out with and then we made a new friend right? I feel like such an asshole whenever this new friend just shifts my friend's attention from me to them all so briefly, talkikf aboht their boyfriend bullshit situation while im out here ranting about how hard its been for me mentally. Its genuinely awful. I then saw both of them watching gameplay without me and sorta snapped, telling my friend that ill be okay and that i have to go. I didnt respond to the new friend's texts because i feel so petty and overly jealous and just so annoyed. Now I feel Horrible because my friend who i snapped at is now isolating themselves. I feel like im in the wrong. I am to some degree but I just dont like my attention being suddenly pulled back so often I dont know what to do. I want to say sorry to them but they're on "do not interact" mode. I feel like such an asshole.
