I’m sorry about your situation. I think your worries are totally valid. There is very little support for carers, particularly post caring.
Are you in touch with any carers support groups? Carers IK, local carers groups. They can be a life line for an advice and meeting people. Your GP should be able to put you in touch.
Are you getting any support? Carers coming in to give you a break? Respite care? It is important to take a break to maintain/build friendships for when caring does come to an end.
Hard question and not one you have to answer here, but do you want to go on caring? I ended up giving up work to care for my Mum for a time. Not 24/7 and not live in. But it took over my life and I didn’t want to do it anymore in the end. Mum had to go into a care home, which was heartbreaking, but the relief at not being her direct carer anymore was intense. There are always choices if you don’t want to continue.
i have gone back to work, so wasn’t totally unemployable but I’ve taken a step back and don’t think I’ll progress much further. I also have a massive gap in my private pension which worries me. I don’t regret my time caring, but it is a massive sacrifice.
What will happen to you when caring does end? Does your Mum own the property you live in or is it rented? If rented make sure your name is on the lease if you can so you don’t end you bereaved and homeless.
Mum died this year from advanced dementia. It is a relief her suffering is over. It is also nice to remember the person she was before dementia took her. Grief started way before she died and I feel like I’m also dealing with the trauma of years of worry as a carer if that makes sense.
No right or wrongs here, just some thoughts from my own experiences. Massive hugs because being a carer is lonely and hard and I don’t think people understand if they haven’t been there.
