Why don't they understand me?

Because everyone has different experiences, needs, and expectations, no one will see the world just as you do. I remember figuring this out when I was a young teenager, trying to help my mom understand how she was hurting me. When I confronted her, I chose my words carefully, I did not let emotion overwhelm my words, and I focused just on my feelings and not on attacking her character. I was as articulate and concise as I could be at that age. I remember being proud of myself with how well I expressed my experiences, and then noticing that there was no new understanding in her eyes. Nothing I said had stuck. I knew she loved me and would move mountains if she thought it would benefit my quality of life, but she could not hear me when I tried to teach her how to help me. That was when I realized that there was no magic word or phrase that would unlock the mental wall/barriers she had that kept her from understanding my perspective. You cannot make someone think or feel what you want them to think or feel. In university I learned that each of us have "cognitive schemas," or rigid beliefs, that filter all information we take in from the world. We have schemas for nearly everything, from the social meaning of different colours to what makes a chair a chair, to more complex concepts, such as the meaning of love and pain, or the roles and expectations for different people (e.g., children, parents, police officers, etc.). Schemas are deeply ingrained, and they automatically affect behaviour and emotions, constantly shaping how we see and interact with the world. But since we each have had experiences unique to us, our schemas develop differently. So, two people can be looking at the same world and see very different things, sometimes making it difficult for them to understand each other.

they don't understand you because they aren't you and you have to understand that you are your own hero. the more you worry about others understanding you, the less you will understand yourself and you will lose yourself, and I promise, it's the worst feeling. sometimes all we ever want it to be understood, but that's the only thing that's seems so impossible. not everyone will understand you, and that's okay, because you are here to live your life, not to make everyone understand :)

Because they have their own issues and baggage. In this world, understanding is rare, fey and fleeting. When you do encounter understanding, cherish it as you would a flower that only blooms for a short time. If understanding is what you seek from others, you will be exhausted and depleted by the quest, for it will never end. Instead of seeking understanding from others, cultivate acceptance within your heart and mind. Accepting things as they are is the only answer, the only understanding, the only wisdom there is.

Many people do not understand what you are going through. You have to explain to them exactly how you feel.

Some people will not understand you because everyone is different and everyone has not experienced the same things.

It isn't easy for human beings to understand that which they haven't yet experienced themselves. They misunderstand or misinterpret you because they have yet to feel the experiences and situations you've been through. It doesn't make them purposefully oblivious or ignorant, they're still learning.

We all have our own visions. That's why they don't understand me. I'm different. I make choices that others consider unusual. That's what make us unique. There are a couple reasons why someone won’t come to the same conclusion as you and they are based on relevance and emotions. Not everyone places the same importance on facts. Just because they may agree with what you’re saying doesn’t mean they will come to the same conclusion as you or place as much importance on them as you. Most people understand exactly everything being said, the problem is they don’t place as much value to what’s being said as others.Failure to understand why that particular person values something so much is the only misunderstanding. No one takes the time anymore to understand why a person values certain things. Everything counts on value of the spoken thoughts, not in misunderstandings.

Is this in general? I'm sorry you feel misunderstood. You're not alone! It's possible you've been associating with people who are actually unsupportive; if you look in new and interesting places you may find new people with like-minded thinking who will understand you perfectly. If this is for a specific discussion: try to put yourself in the other person's position and really try to believe their side of it - this might help you find the words that will this person understand your point of view. Speak calmly and honestly. No one can understand anyone else without honesty! Some people are stubborn and will almost willfully not see your side of things; there's little you can do with these people except agree to disagree and hope for the best for them.

One major reason for the same is you fail to express yourself. You have a feeling that they already know it or how would they react if I told them such and such directly. Feel free to express and it would be alright soon.

We cannot really expect for everyone to understand us, we have to accept that we are our masters we knw us better than others, its is not easy for all to think standing in your shoes.
