((((Kashley)))) I'm sorry, I've been through the kind of grief you are experiencing and I think it's the hardest part of healing.
It's important to remember that part of why this is SO intense and can feel so overwhelming is that not only are you grieving, you are having memories of unprocessed grief. When you experienced the losses you are grieving now, you were a powerless child without the mental or emotional resources to handle this grief and the very people who should have come alongside of you to help you handle it were the source of the grief. So I do know how strong the feeling that you will be overwhelmed can be, but it can sometimes help to remember that you are no longer that powerless child and you do have more resources, so although it feels like it's going to overwhelm you, it actually won't. You can face and process these feelings now, you're strong enough.
Another thing that helped me was to carve out small amounts of time, say 10 minutes, when I could know I would be alone and I would let go and let the feelings come. Sob brokenheartedly if that's what I needed to do. But only for the amount of time I allocated. Then I would have an internal dialogue and make it clear that I would listen to those feelings and not push them away but I needed to wait until I was in a safe place to do so. Sometimes this can press so hard on us, because we've been ignoring it for so long. So when we have to put it away to handle life now, it can help to understand that it's just about staying safe, not about staying in a very costly denial.
Last but not least and I know this is the scariest part, try and let as much of it come in session as you can. The real healing of the grief comes from expressing it with someone and having them be attuned, understand you and provide compassion. That's the part that allows you to move through it and let it go.
I'm sorry Kashley, I know it's extremely difficult, especially because life goes on and you have to deal with things. If you were dealing with this level of grief in the present, people would be much more understanding of you not functioning as well. But fwiw, this level of grief is reasonable for what you are mourning. There aren't many losses that run deeper than our loss of safety, care, protection and love from our parents.
