you are really overthinking mate. You are finding problems, which are not even there in the first place. Its like having a pain somewhere in your body and when you search on internet about what it might be. Trust me after reading on 3 to 4 websites, you will surely end up with cancer as per them. Chill and meditate a little. As soon as you feel like that, no matter what time it is, do a simple exercise which gets your blood pumping and these thought will fade away.
