uncomfortable with my body

i recently went from having 34B boobs to 34DD (i think, they’re likely bigger I’m just not sure). i feel so uncomfortable with how i look and they feel so huge. i hate how they look in pictures. they won’t stop getting bigger and now it’s fucking with my sex life. i live with my boyfriend who i’ve been with for 2 years and i just haven’t really done much with him lately because i feel so uncomfortable with my body and i feel so guilty about it. i just don’t know how to feel comfortable and okay. i had just gotten comfortable with my body and now i just feel so uncomfortable. plus my back hurts now. idk i guess I’m just here to rant and ask for advice if anyone has any. thanks for listening
