If I donated 1 Million Dollars to a nonprofit rehab clinic I had been at, during a hypermanic episode, is there any way to have the money returned?

I had been diagnosed with bipolar disorder in my mid-twenties. I am now 50 and have not been taking medications offered for my disorder because I can't handle the side effects. During a recent hypermanic episode, I donated a large portion of my net worth to a rehab center I had been a patient at in the 90s. The center knew of my mental disorder during my stay. I am now facing bankruptcy because of my actions during this episode which lasted for the last nine months. I am wondering if I am able to ask for the return of my donation to keep from having to file bankruptcy and continue living in my vehicle because I also lost my job, retirement, and any other means of maintaining my life.
