You can read the stenographic military transcripts of his meetings with his generals in the bunker up till the day before his suicide. He is trying to coordinate defense and hoping for a breakthrough but seems also aware that its getting increasingly unlikely and thus is prepared to kill himself once the Soviets get close to taking the bunker as falling into their hands alive was absolutely not an option.
These transcripts can be found in HITLER AND HIS GENERALS: MILITARY CONFERENCES 1941-1945
Someone posted the last 2 days or so of transcripts from the bunker here:

He doesn't come off nearly as unhinged as popular media portrays him here although the infamous chimp out over Steiner did actually occur based on survivors testimony more or less like it is shown in Downfall. That tirade of course was not transcribed.
