It might seem that right now there is little that you can do but revert to your old ways. If you’ve learnt self observation then perhaps you’re used to your patterns of behaviour.
Perhaps you can clearly map out and identify your old ways. And if you can do that then you can also choose a different action. If you’d normally say yes, say no. If you’d normally offer patience maybe try being a little less considerate.
I think too often we fall into this rigid idea of self as though there is something wrong with consciously experimenting with who we are. For example, you could be someone who always listens to people vent despite the fact that it leaves you feeling drained because you think it makes you a good friend.
Instead you could try something different such as saying, ‘I know you’re going through this frustrating situation but I don’t have the space to listen to you vent at the moment.‘
And it always feels weird the first time simply because it’s new, not as an indication of it being the wrong thing to do.
Then, overtime you might find that you prefer your new way of doing things and you can put your old ways aside.
