I have found my people!
Last lockdown I felt that there was much more community spirit- everyone in it together but now, .
Work wise, clients are not as forgiving as they were last April/May and expect way too much. I am trying but I have two young DC at home too.
DH is WFH full time and doesn't seem to be suffering in the same way - he enjoys his job even more WFH, I do not.
I agree re cooking and cleaning. In theory I should be able to bang out decent meals every night but I just cba. We have eaten more fish fingers so far in 2021 than the last year in total.
I have also taken to wearing leggings permanently. I do get out for a walk every evening and I try to mix up the route but some are not really safe at night and I have done all the others to death. I have set myself the goal of walking the distance from Lands End to John O'Groats in 2021 and listening to an audio book per week (I used to love reading but cannot find the concentration now) but even then I am not that enthusiastic. I go out walking to avoid the mess at home.
Getting out of bed in the morning is a challenge- I am grateful DH gets up with the DC. I just need to prolong the start of yet another day, even for 15 mins.
Although this lockdown has only been two weeks (I know!) we were in tier 4 from 19th Dec and we were isolating from 11th Dec in order to spend Christmas with a vulnerable relative (that was cancelled) so we have been in lockdown for over 5 weeks already. At least in the first lockdown we went from pretty much normal life to this, the past 3 months have been on and off lockdown.
The only thing keeping me going is that we are due to move house next month, I am excited about that but at the same time everything is so difficult- getting removals, trying to source a new carpet when the shops are shut etc. Vendor not allowing us round to measure up so we don't even know if some of our furniture will fit (I can understand their reluctance).
I want to see my mum. I want my mum to take my DC off my hands for a day 
I want to get roaring drunk with my friends, over zoom does not cut it.
I am jealous of child free couples that just get to hang out together but then my DC are the only reason to keep plodding on - they are young enough that the routine is strong, even DH's colleagues know 3pm is snack time.
The only thing that helps me is keeping my head down, not thinking too far ahead and getting through one day at a time. I cannot think about when schools will reopen or restrictions will lift, they are not in my control.
