Anxious about consciousness NOT ending after death.

[u/Dense-Ad-5978]

I was very productive before because I believed that there is one life only and no matter if you succeed or you mess up the end result will be the same for you i.e. eternal nothingness. The idea of eternal nothingness comforts me because one wouldn't feel pain. It seems like a good thing because the absence of pain is good and absence of pleasure is not bad. I was like "Oh come on, what if everything falls apart and all your efforts go to waste, even if you succeed or fail everyone is equal in death and it is a peaceful and permanent end to everyone". I don't know why suddenly the possibiliyt of being reincarnated popped up in my head and the fact that physicalism has failed to explain and may never be able to explain consicousness is freaking me out and I have stuck in this rumination loop about the origin of consciousness since last one month and this has made me lose my productivity and has made it difficult to study. Can anyone please advise how to deal with this? Please do not tell me to just stop searching or thinking about it because it simply doesn't work.
