Oh goodness, 8 weeks is still very tiny. Things will stay to get better soon, but at the moment just get through the days. I'd be surprised if anyone really treasures that time, they just think they did because it's all a blur of birth recovery and brain-melting tiredness. Especially if it's your first and you feel like a bomb just went off in your life.
Treat yourself gently. Tiny babies don't need much stimulation, just attention - a bit of time on the playmat, bouncy chair while you do housework, lots of being held for naps while you watch whatever you like on TV. It is hard when they start to wake up a bit and demand your time, and in lockdown it must be almost unbearable. The days are very, very long sometimes.
Definitely get out for walks when you can - as soon as they start to look tired. Aim for a routine, I did EASY too. It will develop as they get older, don't stress if it doesn't happen straight away. If you need the loo stick the baby on the bath mat or in their cot - they might cry and I know it's hard, but you need to attend to your own needs.
If you can drive, maybe do a very short trip somewhere nearby for something different to look at (literally just different streets will help). And good luck - I hated this age, but everything was much better by four months.
