Stalker Sibling Trying To Ruin My Life/ Prevent Me From Becoming A Doctor (location: Florida, Usa)

Location: Florida, USA

Hey guys. This title may sound dramatic. But very long story short, I have kept one of my siblings at a safe distance my whole life. Recently, he has tried to force his will on my mom and I. (I am her caregiver and medical power of attorney, he wanted to take over as being both of those things which my mom and I said no to.)

1. 2 days after speaking to my mom on the phone, he called the police to do a welfare check on her saying that he and the rest of my siblings haven't heard from our mom and I was blocking their communication. He wanted to confirm she was alive... the police came and apologized for waking us up. After we explained the situation to them, they advised that I get a protective order against him. (frequent calls, screaming demands that we listen to him, him saying he was coming in person, etc.) They said the only thing it would do is prevent him from coming over in person and enable me to call the police to arrest him for violating the order. My mom was alright with seeing him if he calmed his behavjor and stopped acting unreasonably. so I didn't get the protective order yet.

2. Not an hour later DCF came saying they got a call that my mom was paralyzed and being exploited. All of which was concluded as unfounded by the investigator. He gave me a case number and everything.

3. Even though I did not file to get a protective order against him, I received a letter in the mail that he filed one against me!!! I called to speak to them about the case at the number on the form but she said basically the hearing is because he didn't present enough evidence to prove a protective order was needed. The hearing is in 2 days. I tried to request to appear virtually, as I can't go to another state and leave my mom. I haven't received confirmation of it being approved yet and the case is in 2 days.

I don't deserve any of this and I am trying to become a doctor. I am at the stage of applications that involve background checks.

For some reason I was under the impression that ever being accused of being a danger to others could prevent me from getting my medical license. I know that I was proven innocent by DCF putting the claims as unfounded and the police also saying the claims were unfounded. However, I think if I can't appear in court there's a chance his ridiculous protective order could be approved! Could this somehow stop me from a.) getting accepted into medical school or b.) prevent me from getting licensed? Idk if the judge would rule in his favor in my absence.

(after he kept frantically calling and screaming on the phone, the non emergency police near him said all they could do is a welfare checkup on his kids to see if he was behaving that way in front of them. They called back saying he wasn't home but the kids were fine and happy and just suggested I get a protective order to prevent him from visiting me. so, my brother filed the protective order against me stating that I made him feel unsafe by calling the police "in retaliation" to him reporting me)

What can I do and what should I do to put this all to an end?

TLDR: My sibling made false claims against me to DCF, the police, and his local court system to try and have me investigated. Everything was unfounded. Will any of it show up on my background check? Will it prevent me from becoming a doctor since I was investigated? If I can't show up to the evidentiary hearing, will he get the protective order against me approved (he is in Indiana, I am in Florida)? And if it gets approved somehow, would that prevent me becoming a doctor?? I am at my wits end with my crazy siblings! I want to be left alone. What can I do to stop this kind of behavior from continuing?
