Hi there. My mum passed away a couple of years ago to a rare blood cancer. My dad had already passed away a couple of years before. When dad died I was stricken with grief but focussed on being there for my mum who had lost her life partner and soul mate. Sadly you can’t heal the hurt but just being there for your dad will be a comfort and the best you can do. I have experienced such a large feeling of loss with both of them gone now - this is all natural and you need to learn to live with that loss. Be good to yourself though - don’t feel there’s a right or wrong way to feel grief. Your loss is still very recent and raw. Hopefully you will find strength bit by bit - it will be a gradually process. The ‘rest’ periods between the intense feelings of loss does increase as time goes on. Take any leave from work they are willing to give you if you feel the need and try not to feel guilty. You are going through a really difficult time at the moment but I would say just do whatever you feel is right for you and your dad right now.
