TWTOM - and the list will go on too. Life won't be perfect, it's not perfect for anyone, but you have so much more to gain rather than lose.
Also accepting that there is and will always be a void in all of us, a void that no one, not even yourself can fill and allowing it as being a part of you and all of us.
I don't know of anyone who in their time of death felt their life was 100% fulfilled. It may sound negative, but accepting that there will always be a part that's missing actually helps me. You can't fill it with alcohol, food, shopping, money etc. just let it be as a part of nature.
