It might be asking a lot to try to remember what it is like to be 16-22 year old range for many of us. But, having raised two sons, this really hits home. As a high school athletic director I lost an athlete to suicide. I could not wait to get home and embrace my sons and tell them that nothing they ever did would make me stop loving them. Young people need to know that your affection for them is not conditional on good grades, athletic success or whatever the circumstances may be. Wanting what you think is best for your children should never temper or inhibit your love for them (even if it is only how they see it).
I often think of a quote attributed to Jackie Kennedy. She said if you screw up raising your children, it really doesn't matter what else you have achieved in life. That sums it up IMO. My boys are adults and by all appearances are successful, healthy and happy. My late wife was a stay at home mother and seemed to instinctively know what was best for the boys. We were very lucky to have her.
