Stay calm, and undrstand that as long as you know that Jesus is Lord, and accept that his word is the fundamental truth, you have the holy spirit dwelling in you.
This is the gift of salvation. Read his prayer in John 17 for encouragement; "I have kept those whom you have given me. None of them is lost except the son of destruction, that the scripture might be fulfilled."
This word will certainly be fulfilled, and no one who accepts and seeks Jesus is lost.
Read Galatians 5, too. Jesus is freedom, and not opression.
Loving your parents is no sin if the love does not interfere with the word of the Gospel. If your parents are christians too, they are brothers, making your love for them especially valid in Christ.
The love of Jesus is keeping his word. You can't love him physically untill you physically can.
Establish yourself in your faith, and take control. Know your mom isn't dead, just asleep. Confusion and doubt are from satan, and not God. Pray for strength, and persistently command by God for those evil spirits to depart from you.
