Is my orchid dead?

[Lilyorchid]

A couple of weeks ago, I repotted my phaleonopsis orchid since it grew a white fungus in the medium. Other than washing the roots, cutting dead ones and planting it in new medium I didn't do anything else. Because of the quarantine I had to go around the backyard and had to make my own medium. I chose pine bark, leaves, and palm tree bark. The palm tree bark quickly began growing fungus. So I replaced the medium with eucalyptus tree bark, which grew a strange black fungus. Now I washed the roots with hydrogen peroxide, and the new medium consisting of pine tree bark, cork, and white stones, and have repotted but I am worried. Is my orchid dead? It lost many roots.
