k. Just needed confirmation.
Blitz

If they sack 4 pawns and a piece in the opening you should win. I don't know of a single good opening that sacks that much material. I don't even know of a bad opening that sacks that much material.

my point is they often play very poor openings (a recent one where I was white went d4 e5 dxe5 f6 exf6 Nxf6.) and I end up with a pawn for nothing... here's the catch... I ended up losing material down the f-file like, 35 moves later after having be put under pressure the whole game. is blitz just about aggression? like, does aggression count for more than in a normal game?
Gambiting one pawn for development isn't terrible in blitz or even regular chess. You get a pawn and your opponent gets some initiative. If you don't like defending such positions, don't take the gambit pawn or give the material back to finish development. Some people like to just attack and if their attack fails they simply lose. I know some players who do that every game, with both colors, because that's what they want to do when they play chess. One way to beat such players is to develop quickly and trade pieces, which will weaken the attack and leave you up a pawn. It's definitely harder to defend against that style in blitz but not impossible. My success rate against such players is pretty high

thank you Knighttour2. "It's definitely harder to defend against that style in blitz but not impossible." this is the answer I was looking for. the reason I asked in the first place was that in blitz I was struggling against this style, but when I play "regular" chess I am able to defeat this type of playing style (gambit pawns etc) almost 100% of the time... I was wondering if "attack" and "initiative" values were enhanced in blitz... the answer seems to be yes.

no I don't... I am also not a premium member, so I don't know what my "real" tactics rating is now... haven't used the one on this site for a long time.

Yes, of course Defending usually takes more time off your clock because you have to be more accurate.
And on that theme of trading position for time on the clock, opening knowledge is more important... at least in the lines where you're willingly going into e.g. the Englund gambit like you posted. That's all some blitz players do, is play their favorite crappy gambit all day long every day. So after a game like that always review the theory so you'll have a solid middlegame position / idea for what you need to do the next time you see it.
so, how do I play good blitz? I am constatly losing to players who sac 4 pawns and a piece in the opening, and get it back while I try to get my king back to safty... are there ego feeders who lower their rating and make a game of "come back" out of blitz? or do I just suck?
