It may be “you” or “them.” I only have your impressions of the situation so it’s difficult to determine with whom the problem lies. It may be you, or the people you are interacting with or both of you.
When you confront someone, your stated goal is to make your message “loud and clear.” I’m not certain what is meant by that expression. By “loud and clear,” perhaps you mean that you’re aggressive. If so, people may find that unpleasant. They may perceive you as being “mean” or difficult to get along with.
When you believe that someone is not “handling their own responsibilities,” I am curious if you tell them what you think. If so, they may see you as being rude. Offering unsolicited advice can be seen as impolite. Your motivation for offering your advice may stem from a true desire to help but realize that not everyone will see it that way.
You also mentioned that you prefer to do things in a very structured way. If you impose this “structure” onto others, they may see you as being too rigid or too demanding. Friends and family may resent having to conform to your way of doing things. All aspects of relationships should be equal. In other words, it can’t be “your way” all the time.
If this continues to be a problem, I would recommend seeing a therapist. A therapist could analyze your interactions with others and then advise you about what you might do better. He or she could also help to improve your social skills.
Finally, you said that you have schizophrenia. Individuals with schizophrenia often have poor social skills. They may not be fully aware of how their behavior is affecting others. Many schizophrenia treatments include social skill-building exercises. If you choose to see a therapist, consider one who specializes in working with individuals with schizophrenia.
I hope this helps. Please take care.
