It feels amazing to have solid acceptance about everything. Alhamdullilah! Initially, it was hard for me to go through that struggle and feel the pain throughout the past 8 years. That is really long for me. Sometimes, when I look back, I wonder how I went through all of that. 
I had been listening to the podcasts from AAplus.co and one of them that strikes me is the one "Finding peace and pleasure in pain." They mention the three levels. It starts from having to struggle and then the next level is having patience with the struggle no matter how it is hard to be patient (and to question Him-that's me most of the time) and the next level is Redha, acceptance. We accept that Allah knows what's best for us and just want us to grow as an individual and ultimately to bring us back to Him all the time. 
Finding peace in pain also means that we no longer question why we have to go through that struggle. Finding pleasure for me in the pain is hard for me to experience because pleasure and pain are the opposite experiences of each other. And I only feel that pleasure when I thought to myself that I will struggle less in the akhirah. InsyaAllah! I told myself that struggling in this Dunya and trying my best to find contentment in all of it is better than struggling so much in the akhirah that will have masyaAllah more impact on us. 
I read somewhere before that there is always a beautiful ending for a Muslim after all the struggles because ultimately, we are closer to Allah when we struggle with certain things as we need  Him 24/7 and I am needy for him and I want to be attached to him and this is a better for me as a Muslim. It will protect me from situations that I will regret. I still love my family and my friends but I must not attach myself to them because they can leave my life at an appointed time. Love without attachment. Yes, I will grief for someone dear to us that left us, especially it can take months for the death of loved ones. But at least, I will be on the prayer mat to ask Allah to help me get through the grief period and go back to Him all the time. (:
