Hi Vegaa122,

Welcome to the forum, very sorry to read your post about your step father. Agree with Billygoat, as you are probably doing, hold his hand, I said to my mum its ok, its ok, I'll see you again, couldn't say the word goodbye. Not sure if your step father is at home or hospital, my mum was at home and we had district nurses come in and they gave us a time-frame, hard as that question is to ask. The nurses will make sure he's in no discomfort. My mum believed in God so I read some passages from the bible, I hope it gave her some comfort. 

Sometimes the breathing becomes more laboured but everyone is different, the nurses should guide you on what to expect. Thinking of you at this difficult time and hoping if end of life is near, it is a peaceful passing.

Don't feel useless, I understand some of how that feels, but you're not, you're a loving daughter. 

Take care
