Acetaminophen and lorazepam

Very nicely done so far. Premise is reasonably believable, unlike most stories here. Your pacing is good and free of extraneous fluff.
I will say this, however: you need an editor. There are a few typo's misspellings, etc, but also a few other small issues; e.g., paracetamol would not be used by someone growing up in San Antonio, or anywhere else in the US. We all know the drug as acetaminophen. There are few more examples such as this, but the story is still rock-solid.
Thanks for the effort.

First, demand that the doctors abide by their Hippocratic oath (first, do no harm). Depakote and lithium are almost worse than the disease. I KNOW! The mood swings can be next to impossible to prevent. For myself, I prefer to control the worst with sedatives as needed. The mood swings are part of who I am. For me, lack of sleep is a definite tell so that I can use some lorazepam to sleep off the worst of the mood swing. You need a cooperative doctor who will help you as a person instead of just another crazy. Sorry.

I very much enjoyed the story, a full 5 stars.
Unlike some, I've no problems with April being a little peeved at the beginning, we can all lose sight of someone's worth occasionally. If she was an ingrate, or it was Charles's grooming, is an imponderable mystery within the story.
Because you didn't make some things clear, or read your own story, or because I'm a pedant.
This was set during the Covid, yet a health centre didn't revert to the default that everything was covid and had a doctor that was free to be dispatched to June within minutes?
In appraising Dr. Satapathy, she was no older than Paul's 39 years, later on Paul is in his early 40s?
Cafés, restaurants sports centres (Paul's dojo) were all open and there is no mention of masks anywhere.
April wearing raunchy underwear for Paul. To be fair, you didn't say Paul's new job was Monday to Thursday, but you did say it was four days per week. I thought Aprils early show on Thursday morning was to prime Paul for the long weekend.
April feeding Paul sushi. No mention made of what had wasabi on it or what was dipped into soy sauce and how Paul told April his preferences. Well, I told you I was a pedant.
The drugs for June were mentioned and Tylenol was included. Tylenol is acetaminophen, which is also used in many cough medicines. Later on in the story, the alternative name for acetaminophen is used, which is paracetamol.
