It can get overwhelming at times. Sometimes when things are so overwhelming you just have to break the "day by day" down into smaller pieces, like "minute by minute". Take some time to breathe, and then you've realized you've just gotten through that minute, and you can make it until the next. Take it on in bigger chunks as you feel more comfortable... "hour by hour" for example.
Try to find things that you enjoy, and focus on that. If there was ever a time to focus on yourself and do something just for you, now is that time.
Hang in there, and keep posting. We're here for you.
