Refusing to eat

I don't know what to do. Ive had my spider Amy for a year now. She's only molted once in my care and hasn't ever since september last year. She rarely ever eats and I always try to feed her. Recently she had been missing for a month until I found her in my bead bucket. She drinks and her abdomen looks okay but she just never eats. Yesterday she did accept a meal worm but did not suck anything out of it. She is an i6 sling. At this point she causes lots of anxiety for me and I want to give her away. She was perfectly fine until her molt with me. I really need help and I don't know what to do. I am thinking of offering her to a vendor I trust to help with my anxiety and hopefully someone who will help her eat.
