I'm sorry that you have been feeling that way. I think your post is very relatable, I've definitely felt that also. Coronavirus has meant that we are isolated more than we have ever been. I think in times like these it is so important to make or revisit our self-care plans.
Do you have a self-care plan? It's just about really discovering the things that make you happy or feel a bit better. For example, I love to watch Korean dramas on Netflix, hug my dog, go for a walk, listen to music.
It can be really hard during this time, I think it's also about thinking about what we can change and what we can't. For example, unfortunately we can't change what's currently happening in the world but what we can change is our outlook and how we take care of ourself.
I hope you may find this helpful! I am really glad that you reached out in the forums because looking at what others have posted, you are not alone in how you feel.
