I'm feeling the same and have been watching more comfort type dramas lately. Hope your life becomes easier. Here's my list of Fluffy or Low Angst dramas: https://kisskh.at/list/1zyQYDg4
At the top, there are also links to other MDLer's lists of lighter dramas.
A Calm Sea and Beautiful Days with You, a very sweet story of two people in an arranged marriage whose main obstacle is overthinking in trying to be considerate of one another. Simple and heartwarming.
My Sweet Mobster, a romcom with an ex-mobster and a children's entertainer. It's silly and cheesy, but I enjoyed watching the tough guy become smitten.
Road Home, a gentle love story between two people whose friends and family were against their relationship.
Touch Your Heart, a romcom that encompasses most K-drama cliches, but Lee Dong Wook and Yoo In Na made them endearing.
The Undateables, a romcom with no noble idiocy. Instead, the couple held hands and said they'd get through things together. I liked it much more than other MDLers.
The above are al K-and C-dramas with the exception of A Calm Sea, which is Japanese.
For comedy, try Welcome to Waikiki and Modern Farmer. Comedy isn't my favorite genre, but both these had heart to them, too.
