Hamilton endured what he described following Sunday's Belgian Grand Prix as "the worst week".
The death of a close aunt on Wednesday was followed by the 27-year-old becoming embroiled in a Twitter furore.
Initially, after qualifying on Saturday, Hamilton referenced acronyms to phrases that included expletives, with the tweets subsequently deleted from his account.
Hamilton followed up on Sunday morning by publishing a picture of telemetry data highlighting the differences between a qualifying lap from himself and team-mate Jenson Button.
It resulted in Hamilton being forced to remove the tweet after a meeting with team principal Martin Whitmarsh, but not before it had been widely re-circulated on the social networking site and picked up by rival teams.
Hamilton's race then lasted just 200 metres as his was one of four cars involved in a pile-up at the first corner La Source hairpin sparked by Lotus' Romain Grosjean.
In need of a boost, as he continues to trail Ferrari's Fernando Alonso by 47 points after the Spaniard was also involved in the crash, Hamilton is determined to bounce back at this weekend's Italian Grand Prix at Monza.
"Spa was just one of those weekends," said Hamilton.
"But the beauty of these double-header races is that it's already firmly behind me.
"And Monza is such a unique and invigorating circuit that it's easy to put my disappointments to one side and just focus on driving as fast as possible this weekend."
