Lord have mercy!
Thoughts tell me that they won't be saved and that I should leave my girlfriend and everyone and that everyone is going to hell and even my to-be-confessor is lying to me when he guides my journey. Please pray for me, I know that prayers help.
The Church makes no proclamation about those "outside" of the Orthodox Church. You have no way of knowing the interior states of your loved ones' hearts, and it is certainly not your place to pass judgement on them. Rejoice, for the Lord is an all-merciful Judge! Pray for your loved ones and be a righteous example to them. Only the Lord can convert one's heart.
Also, your concern that your father-confessor is lying to you, and that you need to make drastic moves, raises a lot of red flags. I am in no way qualified to make this assertion, but I believe that you may be being influenced by the Evil One. He is very skilled at getting us to lose our connection with others and go towards extremes in order to count ourselves "worthy" of God. Do not be concerned, however, as he is powerless in the Light of God. God does not want us to punish ourselves or those around us; his burden is light and true. Speak to your confessor about these concerns, don't be afraid to tell him how you feel. He will be able to give you the best spiritual guidance.
