Welcome to the reality of teaching at the moment!
Remember you are coming towards the end of the longest term, and we are all knackered. Can you give yourself a break from marking homework by setting lots of reading tasks / peer-marked work / marked as part of a starter or plenary?
Depending on your subject there are lots of resources on the TES website (although their forums are now really badly set out!) which have saved my lessons on many occasions. Even if you need to tweak the resource it is better than starting from scratch.
Can you share resources? Eg if another colleague also teaches year 9 can you plan one topic each and swap at the end of a series of lessons?
I feel for you - it can be absolutely exhausting. I worked my way back slowly after about 9 years off - started 0.4, then 0.6, now nearly 0.8 - could you drop the hours a little?
I think "outstanding" is now pretty unrealistic. Save it for the observed lessons, and aim for good (or lower - one lesson of poster work never did anyone any harm!) for the rest.
Hope you feel better after a restful weekend. I'm afraid I had enough of state education and switched to the private sector. Still work very hard, but when the crap behaviour is taken out and the class sizes halved it makes a massive difference. Good luck!
