Why can't they understand what I'm saying?

There are several reasons which most of them reflect back to us. It's either their literally don't understand us in a sense that they have never experienced what we are going through or they just simply don't care to even try to understand. However, there are people who really really would love to understand us and help us. But we don't know how to express our feelings and what we are going through. Plus, more often than not, we don't understand what we are going through too. Sometime we even assumed from the start that they don't understand us and push everybody out completely. It is understandable. And it is also understandable if people find it hard to accept this answer because it involves ourselves. We also play a big part in getting or helping people to understand us.

Sometimes people don't really understand what you are trying to say or don't get where you're coming from. Try explaining it to them in a different way.

Sometimes things are huge, confusing and not quite meant to be understood immediately. Maybe some time, space to consolidate and ponder on how you think and feel is needed maybe? Itll come when its ready, thats okay...

People have a different way of thinking and understanding , Its kind of how our world works . We often say something in our own language and if people translate it in their own , its more often likely to be wrong or grammatically incorrect which would destroy the meaning

They may just be unable to really think about what you're saying. Some people don't listen well to what others are saying. There may be a miscommunication between you and whoever you are referring to.

Unfortunately in life, not everyone has empathy to put view things from the perspectives of others. Some individuals lack the emotional intelligence to be a listening ear. And in some cases, these people don't seem to understand what you say (or have selective listening) because the things you bring up make them feel uncomfortable about things they see in themselves as well. A great way to get people to understand you is to fully understand yourself and the ideas floating around your head first. It really helps to keep your ideas and thoughts on a journal and flesh them out through writing. That way, you can understand your ideas better and present them to others as well.

Because they haven't lived through your circumstances. You have a different way of thinking and an overall different mindset. That's not a bad thing; it just means you'll need to explain a bit more.

People understand different things depending on how they know to. Its best if you can explain in detail what you are trying to say to avoid confusion or miss communication.

At times we want to protect ourselves from getting hurt, so we calculate exactly what we may say to someone, and it is not necessarily the full story or enough information. For that reason it causes confusion for the other party leading them to think you are acting dramatic or attention seeking, when you are clearly not. It is definitely scary to open up to people, but you are going to have to allow at least one person in and take a chance.
