Morning NS
Please don't bottle things up, can you have a dish towel or a coloured cloth that you can have nearby and when you feel a rant coming on you can wave it as you let rip, your mum will know it isn't at her as such but a release of pressure and she may be able to take a step back mentally and listen with a thinking mind not a confused one?
I love the SFA-OYC idea, i often think of my old and first ferret who was an absolute sweetie, very affectionate and playful.
Re the tablets, can you show her you have taken it? you need a fair number given the dose your on to do anything wonky at all!!
I so agree with TW it is your behaviour not you that happened yesterday, the fact that you feel so bad about it shows this, if it was you then you wouldn't have a care about any hurt feelings / unfairness at all.
Do the milky drink and SFA for sleep this afternoon with a tablet before the hot drink so that you can really relax.
Would a text or email to your friend help you? you just need to say sorry for the outbirst yesterday and that when you are stronger the two of you can talk about.
How did it go with the CPN yesterday?
