Will Allah forgive me if the one I wronged won’t forgive me?

I really hurt someone and it messed with their mental health badly. I feel terrible guilt and I’m so scared Allah will punish me. I’ve made sincere tawbah, and I’m not proud of what I did-this is not who I wanted to become. I asked them to forgive me and they said no. I asked again if they could try, and they said they might try. But I’m still afraid of Allah’s punishment. I prayed Tahajjud for them, made du’a that Allah grants them good things and forgives them, and still the guilt won’t leave me. They also hurt me, though not as badly as I hurt them, and I’ve forgiven them. I just wish they could forgive me too so we both find peace. I keep thinking that all my good deeds now will be taken and given to them as compensation, and that terrifies me. It makes me feel like my life isn’t worth living anymore. I just want to feel at peace and be forgiven. I don’t want to end up in Jahannam.
