Feeling tired and maybe a little lost

I have a chronic illness that caused me to have to quit work and study. We moved closer to family because we were promised family support, after we moved we still get no support with school drop offs or pickups and I take the kids to many after school activities each week with no help. My sister in law drops her kids off multiple days a week to their Grandparents no questions asked which enables her to work but we have to basically beg for a night off. My partner works FIFO and I'm just exhausted. I'm constantly asked when am I going back to work or study but I suffer fatigue, concentration issues and mobility issues. I just don't think I would survive going back to work without family support and would probably be on a disability pension or newstart if it wasn't for my partners income, but nobody understands that because they look at me and see someone young and assume I'm ok. I'm so sick of the constant belittlement and judgement from everyone. I'm a pretty darn good Mum and my kids are talented and successful, why is that not enough for everyone in this day and age? Because I think it is enough for me!
