Should i cut off my supply?

Honestly this breaks my heart to even think of, from the beginning i was strictly breast feeding but there became moments where i needed a break so i gave in and gave her formula and i was also worried i wasn’t producing enough for her. I stuck it out for the first 2 weeks of her mainly breast feeding. Now i breast feed her a couple times a day and mainly throughout the night and formula for the feast of the feedings. My supply has declined and now i feel like it’s even a hassle to get it going again or to continue to keep up on it.. and it honestly breaks my heart that i feel like i have to break the bond that me and my baby share while she’s feeding.. I’m just needing some advise/opinions on this.. not really sure what i’m even asking for
