Subjective/Objective

Does anyone else here get the idea that we can't know anything at all for sure?

I guess the root of this problem is that I've let go of just about everything I used to believe in.

Everything just feels so arbitrary.

Yes sometimes I feel like nothing matters, and as much as I want to I don't care about any of the things that used to make me happy. But I think that is just the depression talking. I've just started treatment for the first time, and i am hopeful that someday soon I'll be interested again. Some people have told me to pretend I am having fun, or interested in things and then eventually I will be... Not sure about that tack just yet but I'll try almost anything to get myself back.
Life is worth living, and it is the things we believe in and love that keep us going.

With age, I have definitely become more suspicious of what I think I know and of what others think they know.

I have struggled with this for years.....and it makes me sad. I agree with Rohag, you get older and realize that there is no SURE thing in this life. But, maybe that is a good thing (even though it's painful)...maybe you learn to trust your instincts better. Hard for me to say that it's part of growing up as I am 46 and should already be a grown up!! LOL!

Between Quantum Physics and Metaphysics, there is so much that is a matter of perception not fact.
Schrödinger’s Cat for example (if you don’t know what that reference is Google it, but be prepared for a massive headache trying to wrap your noodle around the concept)

Great one, Mike_J! I can't claim to have an appreciation for that critter, but, as a depressive, the idea of being simultaneously alive and dead makes sense to me...

Thanks for turning my brain to mush, Mike. I'm now just going to sit here and drool while I stare at the wall for a while...

I warned you that trying to wrap your head around that concept would really mess you up, unless you were prepared for it.

You sound lost , like you've lost yourself. It might be a symptom of depression to feel like you arent who you used to be *hug*

One thing that has helped me a little bit is differentiating between my actual experience and things I've read or just thought about. I've experienced the sun coming up every day for 60 years so I'm pretty sure it will come up tomorrow. No, not 100% but I don't worry about the sun coming up. That's another thing; we tend to worry about what we know least? So, when I worry or realize something doesn't seem to be like I believe, I study the heck out of it if it's important to me until I'm again comfortable with what I believe. A lot of "belief" is just opinion though and if you're comfortable with your belief/opinion and why you believe what you believe, it should be pretty hard to shake a belief.

But after many errors, I have learned to stay away from saying anything like, "I would never do X," especially if I've never been in that situation. Anything hard or fast I take a good look at because most things are complex not just one or two dimensional. One can't know the whole of something alive/complex but that does not negate what one does know! People behave differently in different situations, why not light or other aspects of physics, math, etc. :-) We just don't know it all yet and learning new parts increases knowledge, it shouldn't detract from belief. Belief should not be static either.

Last year there was a dead black cat in the road that looked like our cat Deja Vu. My son and I looked at it and I said, I wish it wasn't Deja Vu. When we walked inside we saw Deja Vu on the couch. Since he was simultaneously dead and alive we renamed him Deja Vu Schrödinger.
