I am so overwhelmed that it triggers my anxiety

Hi,

Apology to go off topic for a bit. I just wanted to release how I feel...

I am starting this thread to ask if stress, anxiety or being depressed the same based on your actual experiences? Is emotional breakdown caused by which? How did you handle it?

I have been having a real tough situation way before this Covid19 pandemic happened - I resigned from work and started online freelancing. I am a single mom of a 12-year old boy. I am feeling so down, problematic, worried from all sorts - family, financial, work, household chores - almost everything. Sometimes I find myself daydreaming and overthinking because I am overwhelmed with so many things.

What to do?
