Oh that's rough! Isolation makes it so much harder. Are you in an area where a mental health care plan doesn't get you a full rebate or is the MHCP something you can't access?
Yeah meds aren't for everyone, but it can be frustrating to feel like the stuff that ought to help just... doesn't.
If accessing mental health support is hard, you could always give the Help Centre a buzz - they aren't open on weekends but Mon-Fri, 10am-10pm you can call 1800 18 7263 to speak to a counsellor (or visit that link to book a call or contact via chat or email). We welcome folks to call as often as they need to, especially when it's hard to access other forms of MH care.
When was the last time you gave yourself some time to do something fun, or something just for you? I hear you have so much on your plate right now so it might be a real struggle to carve out that time, but I've found for myself it's more important than ever in these times
