I know sometimes life can be tough, especially if you're trying to figure everything out, or too many things are happening at once or even just existing as a person with relationships, duties, children, etc. It's just hard. Remind yourself that you are doing your best and that you are worth everything good in the world. Remind yourself that you're not alone, and there's always someone out there that relates to your struggles. You are allowed to feel what you feel. Prioritize family and friends, but also tell yourself to take time for yourself as well. Even if it's simple, do a little manicure or get some nice lotions, read a book, and watch your favorite dramas.
Could be anything. I hope you take my message to heart.
