Ask for help.
Now picture being on the other side of it, watching a peer struggle. You want to help, but when the other person keeps saying, "I got it,", you have to either believe them or start managing them. The former leads to continued struggle. The latter leads to a power imbalance and eventually to resentment all around.
Don't put anyone else in that position. Your struggles are not yours alone. Ask for help; you'll be helping more than just yourself.
