am i a bad friend?

so i (f13) have these two friends let’s call them M (m15) & D (f13). they both like each other and i like them both. M and i held hands twice and hugged a couple times. D & i hug and hold hands a lot. i really really like M but D does too. neither of them know i like them but i feel like a terrible friend cause i have a crush on my bestfriends crush. they are both my bestfriends and i have a crush on them both. i feel bad cause sometimes i just want D to leave me & M alone but then i’m like wait no, she’s your friend and i end up hating myself cause of it. i want them both to be happy and they are happy “together” even though they aren’t actually dating. they hold hands and hug a lot and all i can do or say is smile and laugh and say “aww”, “too much heterosexuality” (im pan), “cute.” and other stuff like that cause i don’t want them to know i like them both and i wanna seem like a good supportive friend but it’s really hard watching two people you like really like each other instead of you. :( anyways i just want some opinions on what you guys think?
