Hello @Mon_102
That sounds really difficult, and that you really care about your mother and looking to get some more support for yourself which is great. Are you currently linked in with a counsellor or psychologist at all?
Other than Spectrum you could also look into The Australian BPD Foundation, they have a link to resources for children who have parents with BPD;

There is also GROW, which runs support groups across Australia. They have a list of support groups on their website but you could try calling them to see what exactly the support groups focus on:

It is really good that you are reaching out to the forums for support, look after yourself.
