Positive and negative fluxuations will continue from table to table, dealer to dealer, # of decks dealt to # of decks dealt, and casino to casino.
This is what constitiutes the "streak" phenomena that are session wins and losses, e.g.; 15 wins in a row, 7 losses in a row etc.
Remember, it really is just one long session with breaks that we record. Think of sessions kind of like a baseball season, in that the better teams will have a winning record at the end of the season. This means YOU since you're the better team [as in you have the edge over the casino]. In blackjack, the end of the season only happens if and when you quit playing blackjack forever!
The most important element are your game conditions. Yes there "hot" dealers, as there are "hot" players, players who can't seem to lose, even though you may be. And it's certainly disheartening [only if you question the math and your play] to lose and others are winning, even if it's only the dealer, or lose hand after hand etc.. I admit, this is a learned skill, a painful one, but learned nonetheless.
This, however, IS the game of blackjack, and the only way you WIN is to play where the GAME CONDITIONS INCREASE your eV [mathematically] and that is through the combination of game rules and deck penetration, with deck penetration being more important. [proper bet spread is assumed as well as playing environment]
So, if you're in a 6 deck game with H17, but RSA, DAS, and LS with a dealer who is cutting a deck or less, you STAY and continue to play as opposed to moving to a table with 1.5 decks cut regardless whether you think the dealer is hot or not.
BTW, I find people are more inclined to pose these types of questions or question themselves when their primary games are SD or DD. It matters not, really.
If you find yourself emotionally unable to handle both the losses or the lack of proper betting, i.e.; when a max bet is called for, and you don't push it all out, then your not playing optimally and then you should STOP and not before.
