I think life is harder than I thought it was going to be.
How is life harder than you thought it would be?
It is hard for me to get out of bed in the mornings.
Everyone has responsibilities that must be met. You need to start everyday with getting out of bed so that your responsibilities can be fulfilled.
I'm having a bad day, when will it end?
Everyone has bad days. If you need to then take it easy on yourself for the day and try to find something that'll cheer you up. However not everyday will be good and you shouldn't expect them to.
