It's all coming back to me now

ok it's all coming back to me now it could has two meanings

the first meaning is that lately i had the same feelings i used to have around 2 or 3 years ago; the same feeling of bitterness, but it's so hard to believe that these feelings are repeated or i can feel the same once more, or even worse. is this right or wrong or its just a visit from the past. or the most important question do i seek this bitter sweet feeling. who knows what tomorrow brings?

the second meaning is that now its one of the moments that it's all coming back to me whether to study, work hard or join new activities.

In the end it's all coming back to me
