Hi @Lisa2
I just joined this forum today and your post was the first one I came across. I can say that I understand where you are coming from and you are not alone. I'm a carer for my mum too. She was diagnosed with MSA. (rare neurological condition) a few months ago. It is a mentally and physically exhausting role being a carer and like yourself, I too have struggled to stay mentally positive in addition to having to deal with my own childhood PTSD which has been constantly triggered by her. It is really hard, like youself, I want to give up at times, however I know its not an option. I have a few practical advice I use myself which i will share. Hope you find them helpful.
1) Self-Care, as cliche as it sounds, self care is really important. And when I say self care, I'm talking about doing activities that contribute to brain health (feel good factor). Exercise is one as it releases dopamine and endorphins. Also simple act of going for a quick walk for sunshine and fresh air does wonders. Also, make sure to eat well. Those things are important to help you get through the day.
2) Professional help - Engage in a good mental health professional. My experience is that good ones can be hard to find, and still there's the issue if you vibe with them or not. However they are out there, you need to just persevere, ask your GP for any recommendations
3) Hobby/passionate cause - Pick something you are passionate about and visualize this as part of your future. Example, I. working towards being a designer, so everyday, I make an effort to work towards that. Even if it's as little as 30min, every little bit of work contributes to your goal. Put on some uplisfting music when you engage in these activities.
4) Boundaries - know that you are doing a great job. you should be very proud of yourself. But to take care of others, you need to take care of yourself first. So you need to be able to set boundaries. You can't take care of everything, and many things are beyond your control anyway. So draw that line where you are comfortable to say to yourself, "I have done enough, and I am okay with that" The situation is not a bottomless well.
At the end of the day, I really try not let my current situation define me. I know no matter how hard it gets, tomorrow will be a better day, it's not forever.
Take care! x
