Nobody would ever say that having a disability is easy, however accepting circumstances will teach you to cope. One of the first steps to acceptance is organizing yourself. If you look at areas like your lifestyle, body and room you will find that when that is organized you lower your stress levels and build confidence. Accepting help could probably debilitating, yet you should learn to actively and graciously accept help. This also mean that you should not get trapped in a bad situation, but use good alternatives when you deal with people that are abusive, cruel or patronizing.
Something to consider is to relocate and moving to an area or city that has excellent resources in order to aid people with disabilities to live independently. Many organizations, hospital programs and counties have programs set in place to help the disabled to close gaps in caring for themselves. You might find personal assistants, drivers or people running errands that love doing things for others.
Another very important factor is regular exercise. Even people without the ability to exercise should participate in mental exercise. Something a disabled person learns quickly is that many abled bodied individuals are nervous around a disabled person and do not always know how to act. Instead of losing your dignity rather remain calm and polite and educate ignorant people while demanding respect as this is a sure way to build courage.
Allow yourself grieving time if you went from able bodied to disabled by seeking help by family, friends, counsellors and therapists. You will learn to distinguish between pity and support, you do not want pity that is for sure.
Accepting your disability is hard and often discouraging. You have to accept that you can still enjoy life even though you might not see, hear or walk again. Some forms of disability can be altered with treatment and physical therapy and that is something to seize and fight with. Taking advantage of possibilities such as limb loss where prosthetics can alter your life. It will not change the disability or reverse it, however you can improve your life significantly.
Seek out disabled people in your condition or similar communities as they know what you are going through and they truly understand like no one else.
