Find some healthy sensory experiences that you can enjoy right now. Take a walk, feel the breeze, pet a dog, have a nice meal, listen to music that you love. Your basic senses are trying to heal you.

The thought that "your problems are permanent" is just a stupid negative thought that keeps coming up because it has a strong emotional content. Everyone has the power to change.

Don't wait for your CBT to figure out how you should get better. Get active. Find what works for others. Keep trying new things. Actively trying new things in itself will help.
