It's the other way round. Acceptance does not change the facts. Moreover, panpsychist monism is BS and consciousness being the ultimate reality does not mean that you can change facts with your mind as you please (that's another BS assumption and both fall into the category of bargaining).

All what acceptance accomplishes is that you don't see facts through the psychological filters of your individuality. And without those filters you simply cannot claim that our mortality, life, etc. are absurd and tragic, because that's clearly not the objective nature of those facts.
