How can i better understand what people with disabilities are going through?

Honestly, there is no way of truly understanding what a person with a disability goes through unless you can relate and/or have a disability of your own. Trust me I know. I have a birth injury. I'm now 20 years old and honestly I don't really think anyone understands it better than others with disabilities no matter how much we try to get other people to understand.

You just need to communicate with them, and after a while you'll when they become your friend you'll understand them

I think it's difficult to fully understand what someone with a disability goes through until you go through it yourself. However, things like internet resources, working with people who have a disability can really give you and insight into living life with a disability

They might feel alone at some point like nobody understand them and it can be frustrating from time to time.

Spend some time talking with them! Most people with disabilities are open for such a talk and are happy to share their experience with others! Another way is to try to recreate a situation of a disabled person like trying to write while wearing a boxing glove. You will never experience the whole struggle but you can somehow relate now.

Read blogs and books written by people with disabilities (NOT written by the parents or family members of disabled kids--that is not the same thing, no matter how much parents might try to convince you that they understand the disability better than adults who have it).

People with disabilities have such diverse experiences that it's probably not possible to get a meaningful sense of what they're going through as a group. On a personal level, understanding what a person with a disability is going through is much the same as trying to understand what a person without a disability is going through. Spend time with the person, talk to each other (find a way to communicate with assistive technology if needed), and get to know one another. If you earn the person's trust, they might open up and share their experiences with you. (They might not want to share and of course, that's up to them.) Unless there are specific reasons to do otherwise, treat it as you would any other relationship.

One way to learn the situations that those with disabilities are going through is to work with them. One can help by doing things such as volunteering at places that serve those with disabilities. Reaching out to your local resources and alliances can help you get on the right track such as local hospitals, nursing homes, shelters. It might also serve to be a very rewarding experience.

To an extent, you need to put yourself in their shoes. It won't come remotely close to what that person is feeling inside and is beating themselves up for, but at least you're getting a glimpse of how it would feel to be them.

Ask them. Every person with a disability is different.
