You really need to sit down and discuss this one on one with your Priest.
The following is my personal opinion and belief. If I’m incorrect I hope someone will correct my error.
I believe it’s from the apostolic succession. The new priesthood was founded by Christ and passed down by the Church. One must be ordained to stand in for Christ in confession and at the consecration of the Eucharist.
I can tell a friend about the sins I’m committed. The best they can do is say that if I’m sorry they know God has forgiven me. One of the blessings of going to confession is that I can verbally hear from God that I’m forgiven through the words of the Priest.
I am an EMHC for the sick and home bound. I haven’t had the honor of bringing Our Lord to anyone yet. I just received the pyx I had ordered and when in training I asked if I could keep two of the unconsecrated hosts. I wanted to practice removing one without my fingernails chipping off the edges. There is no way I could take one, say the Eucharistic prayer, elevate it and have it become the Body, Blood, Soul and Divinity of Christ. One, because I’m female and Christ is male and two, I’m not a priest. I’m not ordained and never will be.
Again, please speak to your Priest.
