Good Lord, do not deload your squats by 45 lbs if you are making progress on them. No, no, no.
How tall are you? Even if you are short like me (5'4-5'5ish) then 165 is pretty small. If you are over 5'8 or so then you are an undernourished Somalian pirate. Either way, even if you are short, all this would be a lot easier at 185 lbs.
You also need to microload. 5 lb jumps on press/bench is too much when you are light. Get some fractional plates and start making 2-3 lb jumps.
If you get stuck don't reset immediately. If I have someone only get 4 on a given exercise then I have them do 4x4. If they only get 3 then I have them do 5x3. In other words, I have them get their volume in, and then the following workout we work on adding reps until they make 3x5. Sometimes it takes a few attempts to get it.
