Anyone else feel like they have wasted their life?

I think the title says it all, but I will explain a little more. And I'm not meaning to be doom and gloom, but I'm 48 and I feel like I wasted so much time. I've spent the last 20 years in an abusive relationship and now that I'm free of it I just feel like I've lost so much that I will never get back. Yes, I have children,they are all almost grown and doing well in life, so for that I am proud of my part in raising good kids. I also have many health issues now that limit what I can do. So I feel like I will never have a real loving relationship, which is something I've dreamed of my whole life. I'm working on me, and learning to be on my own, but I don't want to be. I'm just afraid it's too late. And I regret spending so many years not respecting myself. Anyways, can anyone else relate?
