When I was in high school and college, I played sports. While playing, I hurt my shoulder so bad that i had to sit out, go through therapy and then become cleared to participate again. Now my injury was so extreme that even today I have pain in my shoulder while doing certain things. Upon being cleared, the doctor gave me a list of things to do so that I could continue to strengthen my shoulder as well as some activities I should take caution about. When you are healed, there may be some side effects that may come that causes you to feel the pain again.
On the contrary, with restoration, it turns something that was perfect, then damaged, back to perfection again. It doesn't have side effects, and pain will not come if something reminds it of it's past misery If you are restored, you go back to your original condition. Your heart is full and complete. There is nothing that can bring you back to your former pain. You may remember the past and what you were involved in, but the pain is not attached to it.
I encourage you to ask God to restore your heart from what was taken or given away. I promise you, He will do that and more! Just trust and cling to His word and His promise for your life!
