Time for you is relative to your movement. You experience time because shit is moving inside of you. By shit I mean each particular atoms that build your body.
If you'd be close to a light speed, entirety of you would move in that speed. So for yourself the time is normal. One second is one second.
For someone observing you from earth, you'd blast the universe and after an hour you wouldn't be visible any more.
For you tho, it's not even a second.
Time is movement. No movement no time. If something moves then also time changes. If all your atoms would stop now you wouldn't get older. Also you wouldn't think any more and you wouldn't notice any time.
Ps. I was at the same state as you some year ago. I've spent several hours absorbing this topic and eventually it clicked. Take your time.
