Hi Sharona,
I do hope you've been able to get some support for both your son & (very importantly) yourself.
I come from both the perspective of a carer (adult daughter with Bipolar & Borderline Personality Disorder (BPD) & partnership/peer support worker, working with carers. Let me tell you, when I first started actually working with carers, I was truly amazed at how our stories were so similar. The feelings of being isolated, lost, depressed, physically exhausted, confused & frustrated. Not knowing where to turn. I was fortunate to have a very knowledgable & caring GP in the beginning, who, after me blubbering my way through telling her my daughter's 'story'; said "and what are you doing for YOU? Who is supporting YOU?" It's such a hard thing to accept that as carers, WE also need support (emotional & sometimes physical), access to appropriate services & opportunities to vent OUR frustrations, concerns & hopes (for ourselves AND for those we are caring for).
By doing this, we prepare & protect ourselves, as carers.
Sometimes, when things get hard with my daughter, I (now) feel like I consciously 'put on' my carer suit/hat. Like an armour that 'protects' me from the abuse/emotional hurt of a psychotic episode & which helps me to focus on what I need to do - whether it's to cart her off to hospital after self-harm, call appropriate services (CATT) etc; or just to stand my ground to ensure both she & I are protected & move on to the next 'phase'.
I also relate to what you're saying regarding your family/friends not supporting you, or not knowing 'how' to support you. Been there. But eventually accepted that there really wasn't any alternative - noone else could really help me in the physical 'being there' sense - although my lovely sisters offered to help out, they couldn't come in the middle of the night or even during the day due to their family responsibilities. Not having a partner (haven't found one yet who could cope with the emotional stress & demands..), my elderly parents were my initial emotional & physical support in terms of being my comfort & shoulder to cry on - as well as my daughters. They also spent many hours sitting in hospital EDs waiting for psych assessment. But after a year or two, I realised this was a burden on them they really shouldn't have to cope with. So I finally had to work out who could be there for me in the emotional 'being there' sense. Some of who are family, some are good friends, & some are professionals - support workers (both mine & my daughters), & really important because many of us are travelling similar journeys; other carers through forums & groups (such as COPES, here or groups of carers who come together regularly in your region).
As other forum members have pointed out; there ARE people out there who can support you in your caring role. Your own GP is the first person. They can organise a Mental Health Care Plan for you (please don't be put off by the 'mental health' bit. Think of it as 'wellbeing' - emotional & physical.... This plan will open doors for you to heaps of support services to assist you in caring for your son.
I'm not sure if it's ok to pass on the details of services in your area (as don't know where you are), but again, your GP or local community health service can help you there.
All you have to do is ASK 🙂
Best wishes to you - you're not alone.
