Actually checking on the Internet gives an indication that you don’t have to make this decision alone, not all at once: I picked up these steps from the website listed below, and it made a lot of sense…but I don’t know if it helps you. God bless you, anyway
"Pray about your vocation. Take any feelings or advice that have led you to consider the priesthood and give them to God, then wait patiently and openly for a response. Realize that everyone has a vocation and if a person is truly open to theirs, God will reveal it to him or her.
Talk to your parish priest, your diocese’s vocations director, or the vocation of a religious order if you are familiar with them. You can get in touch with the vocations director through your parish or by looking in your local telephone directory. A quick Google search of the term ¨Catholic Religious Orders¨ will give you lists of different communities of priests such as the Jesuits, Dominicans, or Oblates. Also consider Missionary Priesthood. These tend to focus on cross-cultural missions where you live among the poor and disadvantaged. They will talk with you about your vocation and possibly get you on a retreat specifically for men discerning the priesthood.
Go through the application process for the seminary through your diocese or through the religious order. This process usually includes several questions about yourself and your desire to discern the priesthood.
If you’re accepted, go to the seminary. Unless you’re somewhat older, you should expect to spend at least 6-8 years there, depending on how much college experience you have. Typically religious orders have a slightly different formation process, based on their own needs. Check with them about the exact steps they take that lead to ordination.
While you’re there, continue to pray and discern God’s will. Above all, do what your rector, bishop, vocation’s director, or other superiors ask you to do.

I’ll pray regarding your parents.
A vocation that amazed me was of a Jesuit who was the only child, only son of a non-believing couple. If that can happen, anything can! God bless your parents and help them to accept whatever vocation the Lord desires for you.
