Awww hun @Snowie ,
It sounds like what's happening for your mum is huge for you. Is she still at home or has she moved yet? I'm sorry if I haven't been up to date.
Transitions can be so stressful. Not just for the person, but those around them.
Do you think this is still the feeling of guilt, or is it just the pressure of everything that is happening?
Hugs to you @Snowie
