No it is not permissible!! From the sunnah is that a person should not ask for death. Why? Because, living, if a person is a sinner or kaafir they have time to repent and a believer has more time to do more good deeds. When a person dies, all his deeds stop and except in 3 cases. IF he leaves a beneficial islamic knowledge that others benefit, the he makes something from dunya that others beneift (ex. car, road, water wells, masjid, etc.) or a child who will make duaah to Allah for him/her. What you can ask is "Allah let me live long as long as you will be pleased with me and my life is better for me, and take my life only when you are happy and it is good for me.
However, i think only people who do not really believe in ALlah subhanahu wet'ala and have no hopes nor patience in His tests fall victims to this attitude. A muslims who knows His lord, will never ask Allah for death. How many of us are prepared to meed ALlah the lord of the worlds, the angels of death, seeing jahannam with own eyes?
That is the statement of shaytaan. He wants you to loose all hopes in Allah.
Pray to Allah azzawajal. The sahaba used to be affraid what their end will be when they die. Even resulullah

who was forgiven all his previous and future sins was affraid of Allah and what will be with him that is why he worshipped Allah until his feet would swell.
Eliminate those crazy thought of your brain.
Allah subhanahu wat'ala says in the quraan about shaytaan when bringing you evil thoughts to say in suraah mu'minoon (ev kema qale)
وَقُل رَّبِّ أَعُوذُ بِكَ مِنۡ هَمَزَٲتِ ٱلشَّيَـٰطِينِ (٩٧))
97. And say "O my Lord! I seek refuge with Thee from the suggestions of the Evil Ones.
وَأَعُوذُ بِكَ رَبِّ أَن يَحۡضُرُونِ (٩
98. "And I seek refuge with Thee O my Lord! lest they should come near me."
