Transitioning to formula and feeling a little emotional

My baby boy is 7 weeks can some one uplift me please I’m wanting to do formula from now on as I transition him over and wean him off my breast milk I feel kind of guilty and bad. Tell me formula isn’t poison and he will be just as smart and healthy and at least I did the 7 weeks. I have many reasons for my decision and have made up my mind but it’s still kind of sad. I hope we have the same bond, he’s suchhhh a mommas boy
