Let me explain to you a very important fact about Islam. Islam is a religion of ease not difficulty. When you come-up short after having done your best, don't worry about it. Take the shortcut. It is permissible. For example, if it is impossible to participate in the congregational prayers at the mosque, or the mosque is miles away from where you live, pray at home. If you are on a fourteen-hour flight in ramadan or you are ill, and you can't fast, don't. Fast another day. Also, if you can't find water anywhere to do "wodou" (ablution) then use "tayamoum."
Under extraordinary circumstances, you will always find a way-out supplied in the Quran or the Sunnah.
