Few people actually want to receive health and disability benefits; most of us would rather be working. However, you have a right to seek these benefits if you feel you need them. If the government makes it difficult, don't be afraid consult with a legal specialist to see if they can help.
Lawyers may be expensive, but issues involving health and disability are complex, and change on a regular basis. For this reason, you should seek legal help if you get in over your head. Fortunately, there are many firms who specialize in the field, and you can probably find one in your area with a quick Internet search.
