I feel exactly like this! There is a popular misconception that those of us with living parents and partners don’t feel this way. I have just had a health scare after my first mammogram, it’s resulted in an operation. I feel really unsupported by both my husband and my parents. He dropped me at the hospital whilst I watched others with someone supporting them, I’m independent and don’t need that but the offer would have been nice. Yesterday, I had my stitches checked and he completely forgot about saying hope it goes ok, or how did it go? This has really made me reevaluate where I am in life. I suffer with mental health issues but plough through, working full time and appearing ok. It’s the feeling that no one really cares, which has always been my trigger, it’s just being confirmed for me at the moment.
