Welcome April30, you have just started your journey to "feeling better" and I congratulate you for reaching out here to get some comfort and support.
What you are doing here is the very begining of a healthy healing process....writing..I credit a journal and being here to my grief healing and I can truly say that this community has brought me out the other side of grief.
Start with sharing here, if you feel comfortable, you can get out how you are feeling and get some feedback and support and tips on how to move out of this space and see if they work for you, there is no judgement here, just love and care. Also a journal I found wonderful, you can write perhaps some of the more raw feelings that may not be suitable for here, to blame to purge and to get it all out, it is for no one else to see, just you, gee it feels wonderful to have it out.
You might find that is enough, just the sharing and purging, you might find you need to seek some professional help from counselling too. I found this to be so amazing, I learnt so many things as well as things about my self and also techniques to manage conversations with others that I was struggling with....wonderful.
Feeling heartbroken is just so painful and I am so sorry that you are going through this, I think people give advice with the best intentions "sit with it", but yes sometimes fail to go deeper to give suggestions what that looks like to "do"..I hope my suggestions have been helpful to you.
I think also try to do some things that do make you smile, that you love to do, as much as possible in these times of physical distancing, which I am sure does not help either.
Hope to chat to you some more
Hugs to you
