“too scared and tired to continue therapy”

Don’t quit yet. You may need a lightening up in the amount or pace of therapy work you’re doing, but therapy is the best and safest place to deal with fear and weariness. Tell your therapist how you are feeling, and together you can work out a change of approach that will help. Remember that therapy will take you to unpleasant places before it will take you through them, but it’s better than hiding from them.
