Fear of eternity

Fear of Eternity

I'm 15 years old, Catholic by birth, but truly converted a year and a half ago.

I have a problem that has plagued me for a long time, which is: the fear of eternity.

I don't know if it's a common fear, but it's something that really shakes me. It's illogical, considering that heaven will be good, but I still find myself thinking of it as something negative.

Since I was young I've had anxiety, maybe that intensifies this fear, but I would like some material, study, word or support that could help me. I recognize that it may be a lack of faith in God's goodness, but it's something really difficult for me to think that in a billion years I could still be doing something cool and truly happy.

On the other hand, I also recognize that it would be even worse to simply cease to exist.

I have no problem acknowledging that the world will be eternal, I accept that, along with the other dogmas and teachings of the Church. My only problem is with this idea of ​​how vast eternity is, and how good it truly is.

Thank you in advance, and I ask that you pray for me and my mental health.
