You will get that talent back. And when it does come back, you will appreciate it more than someone who never lost it. And that will give you an edge as an artist that few have. Going mad is another one, so double good for you!
Here are some of my life drawings and figure studies from the last two weeks. I take classes again at the art museum since November and work on it when my 2 year old is sleeping. These are skills that i never thought i could regain - i am a different, but better artist than i would have been if id never taken invega , and the same will happen for you if you desire it

You can take APs during the time you're recovering if you need them, just don't get an injection. AP pills don't have the lasting effects of invega sustenna once you stop them. I took AP pills for a short time when I had psychosis again, but they did not affect or lengthen my recovery by a noticeable amount once I ceased taking them. Plan for what will happen if you have a psychotic relapse to ensure that you are not injected again.
4 injections are very few. Diet and exercise can help you, but the truth is that while finding a "lifestyle" to help recover can help give you a positive mindset and help you feel in control, nothing will actually cause recovery but time off the drug. Expect to start to feel "yourself" again around 9 months, and all of your intelligence, creativity and talent to be back within 2 years.
I'm glad you found hope here, this forum also guided and gave me hope at the time when I was recovering and felt hopeless as you did
