Evidence to support that nothing matters... There is no evidence, it's just a feeling.
I'm gonna be really annoying right now. Bear with me while I throw some CBT your way...
It's a thought - so, the thought is "Nothing matters". The emotion that then follows is "numb" or "dead". Following that, you might have what's called a 'secondary emotion' - otherwise known as 'feelings we have about our feelings'. Reading between the lines, I think yours might be worry or possibly hopelessness.
So: the thought is "nothing matters".
I get this thought, so I'll give you my version of evidence to support it:
- the career I spent 20 years investing in is not where I want it to be
- I have no family
- I have no support system
- I'm not ever going to find a partner or get married
- I can't have children
- People only find me valuable because I'm useful to them.
And, here's some evidence against:
- My cats need to eat, and go to the vet, and have a good life - they matter. If I don't do my part, they suffer.
- I do have a role here on the forum, and it matters, I think.
- I helped a student today
- Someone I know is in distress, and they want someone to talk to tomorrow. I can do that for them. It's not being used, because I'm looking forward to helping. Helping matters.
- This is the life I have, for better or worse. It must matter, because I struggle with it.
I'm always good at more evidence for than evidence against...
And now, after doing that, I check back in with the original thought - and I ask myself, "how much do I still believe nothing matters? How much have I changed?"
In this example, I started with believing it at about 80%. Finishing the exercise, I believe it at around 50%. And I do feel some relief.
That's a super-short thought record, which is one of the tools in CBT. I'm a very flowchart-style thinker, and also, really, I just think. I think a lot. So, this kind of stuff helps me. In one way, it calms me. In another way, it gives me a structure to walk through my bothersome thoughts and challenge them. BUT - I still get to believe they are at least partially true, if I want. They are maybe just a little less true, right now.
Being able to believe they are partially true, still - or even majority true, frankly - keeps me from feeling like I'm just being a good student by doing the work and then saying, 'look, I'm all better' - I'm good at being a good student, and it's not very good for me.
No clue if any of this helps, but hopefully it at least passed a bit of time for you. :)
