It's actually what's best for your current life. There is a beautiful side to death. Imagine knowing your old life completely, all your pain, memories, family, friends and their deaths. When you are strong enough to handle it, it will come to you automatically. Be sure that when there is something you need to know from your old life that will benefit you, you will know it. Don't beat yourself up for this, it's not impossible and whether it's something you need to know or not is up to you.
Death is a blessing. I don't know how else to explain this. A blessing given by the universe for our development
