You have the right to act on your own behalf to make good choices. Everybody has dignity of choice.
Some people want to blame others for their mental state or current circumstances. It’s true, we contribute to each others experiences, for better or worse. We have problems which other people contributed to, but we are responsible for helping solve our own problems.
Change your own mind
No one else can change your mind. It is your mind to change. Sometimes, people’s brains have been injured and, if that’s the case, they need to see a doctor, such as a neurologist or therapist. Clinical hypnosis has documented evidence of jump starting healing processes which the brain already knows how to conduct. Of course, there are limits, but don’t limit yourself before you even try.
“There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance—that principle is contempt prior to investigation.” —Herbert Spencer
You can do more
The human mind is capable of so much more than we give it credit. You enable other people’s bad choices by feeling sorry for them. Pity is a toxic attitude to convey to another.
Do you know the story of the 3 frogs who sat on a lily pad? One decided to jump. How many were left? Three. The one only decided to jump but didn’t take action.
Make a decision and follow through with it one step at a time and see what happens. You can always go back to the way you were but I don’t think you’ll want to.
