You are so right! The depression can really take hold of us, and being able to do something simple on our own chases those blues away! I have never for one minute regretted not having PT. Being able to rehab myself by myself has brought me peace of mind. Many on here go to PT just to get out of the house. But, I had no one to drive me and taking care of everything kept me busy anyway. The times of rest, icing and elevation were a wonderful relief. Of course, the first couple of weeks were really rough, but as my activity increased, so did my sense of accomplishment! You will do just fine without PT. Go, if you want to get out, but you don't need them physically. Keep enjoying those hikes, but be extra careful to not overdo or trip! Uneven ground is hard on a baby knee. You know what to do when you hurt! Just know that each week you will see improvement. It is a slow process but the end is there!
