focus more to try make things less garbage for other people that have it garbage and who you can relate too. you wont have children but your ideas can live on as your progeny.
there are many internet dwellers who will not have children but will have a far more profound impact on the world from just making and spreading memes, which can sometimes reach huge audience and butterfly effect into painting artists in europe, or other such things to bring about a world that is just and wholesome with good things and not the bad things that normal kind do promote.
frame your reality. did you lose out of normal life, or did you get given a secret gift, when at the end of your life it will be explained that it was given to you to ascend. maybe you only rot in the ground, who can say. i believe there is more personally. find meaning in this, however you can, reframe things to realise that its not a cope only, that we do have a rare and precious commodity of time and thoughts and thinking, deep introspection that masses dont get, on another level, and that adds something. you can be less than or you can be more than, or you can be a human having an experience and ride it out.
what if all this was going to be turned around one day, but it didnt, and at the end God gathers up all virgins and says hey, well you know that i was about to turn it around for everyone else and make the world a fantastic place for everyone except, you didnt do your part, see anon, a year before you caught the bus you were going to interact with another anon who would go on to do something which then led to a change in the world and it became a paradise utopia, but that will not happen now and you chose that yourself for others.
there is a whole world of mental framing out there that exist to make yourself into more contented human, and less suffering, that is important to work on before throwing in the towel. remember there are people here that dont even have any what you have and they still going.
nefer giv up.
