everything is always too much

Hi I (28, F) have always found life too overwhelming and especially more so in my adulthood. I was recently diagnosed with combined type ADHD, as recent as 2 months ago and some things have started to make sense but I wanted to reach out and ask if others feel the same way I do?

For the past 3-4 years if not more, I find everything overwhelming. Waking up in the morning, getting dressed to go outside, putting makeup on, taking it off, seeing my friends, all of it. I feel constantly tired, like there is this weight on my shoulders and no matter how much I rest, I don’t feel rejuvenated. I also have PMDD which derails everything in my life and it seems that ADHD meds also don’t work during this time.

How do I get out of this never-ending feeling of tiredness and overwhelm? Just looking for any advice or if someone else feels similarly and how they cope.
