Stealing / shoplifting

Hello , i’m an 18 year old girl who’s had a tough relationship with god since 12 years old. To start off i suffer with mental illnesses one being hearing voices and having episodes in these i tend to steal while at shops or something bad will happen i try nd remind myself god wouldn’t let that happen. But it fails. I don’t know what im looking for maybe advice or somebody to tell me god will forgive me. I feel awful. I don’t know how do i make up for this ?? what can i possibly do. I feel like a horrible person i got caught stealing today.
