You show a lot of spiritual maturity in your decision to respect and honor hour mother. The Bible is very clear that we are to honor our father and mother (Ephesians 6:2). In fact, there's a promise that goes with this command (Eph. 6:3). However, honoring your mother doesn't mean you have to obey her. Obedience is for children (Eph. 6:1). Sometimes as adults, we have to make a choice between obeying and disobeying if one of our parents is asking us to do something that's unreasonable or wrong. For example, if your mother was asking you to stop going to church, you would not be obligated to obey her.

However, it doesn't sound like she is dong that. As you said, she feels threatened and betrayed. That reaction probably comes from her own insecurities and has little to do with you. She probably feels like she can't control you, and that can be frustrating.

Truth is, you have made a wonderful decision to follow Christ, and that can be threatening to some people, especially family members. If it's necessary for you to continue to live at home, don't feel bad. On the other hand, you need to live your life of faith without fear. Ask God to give you grace and strength under pressure, and pray for your mother, that she might also feel God's love.

When it's possible for you to move out, you will be able to do so with your relationship with your mother intact. By honoring her, you honor God, and he will bless you for it.
