As Sirk mentioned, there are seasons to our growth. I believe the impulse to throw yourself into study, etc. is God led. As long as you are not neglecting the people in your life. Obviously, you need to drink deeply of God at this time.
I think you will find that eventually this spiritual fervor will subdue a little, and you will enjoy the things of creation such as travel, books not necessarily of a spiritual nature, gardens, mountains, beaches, and the work that you are gifted with to do in a new way. And just plain have fun with people.
As for witnessing, naturally you want everyone you meet to see what you see. However, this calls for discernment and prayer before you do. You should be led by the Holy Spirit in prayer, not by your own feelings. He will give you the wisdom with this. Some people need you to listen to them first. In other words, show in some way that you accept them before they will receive what you have to say.
We can talk and talk about Jesus being real to us, but unless these other things are in the picture, it can be a turn off. And only the Holy Spirit knows when a heart is open to receive. We waste our time trying to convince people of what they should believe. We are to speak to their hearts when we discern they are seeking.
