What do you do when you don’t know who to turn to and what to do and it seems like all is lost ?

Well there is always someone to turn to. You have to be willing to let them in..No matter what you're going through all is defiantly not lost. Everything will work out the way it should in the end and if it doesn'tMaybe it's not the end. Ik it may seem hard at this age, but ik there are things worth fighting for. Just be brave and fight for that. :)

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
