What would make someone not allowed to buy a gun?

Anonymous

I was sectioned before as a teenager and I was told by a friend that this might be an issue. I want to own a gun because with all these shootings, I want to be able to do something about a murderer should the need arise. I would like to be able to carry in public because as long as I practice shooting accuracy and get a safety license, I know I can trust myself to defend myself and the public should it be absolutely necessary. Does anyone here have a gun and how did they go about the legalities and courses or whatever else? Can someone with a history a long time ago of being a “danger to myself” and currently on SSRIs be allowed to own a gun? I would feel really bad if I was discriminated against and not allowed to.
