So sorry you’re going through this Theodora. You don’t say how long you’ve been widowed. I lost my husband five years ago and although I’m in another relationship now, the loss is still there and probably always will be. Grief is a journey and from your posts it sounds as though you’re in the early days.
I think maybe your sons are having a hard time coming to terms with the loss of their dad, and so, emotionally, don’t have much left to give to help you. They need to know that the type of grief you are feeling is different to theirs. They may have lost their dad, but you have lost your love and your life partner, and the grief is a physical pain, which at times is overwhelming. It’s not just the person you lose - it’s your whole way of life, and you have to come to terms with this in your own way. Your sons have their own families and they don’t have to adjust to living alone and rebuilding some sort of life.
Everyone handles grief differently, and grief counselling may be helpful. But that’s your decision, and in the early days after a loss, it may be counter productive - you need to be prepared to engage with it fully to benefit, and sometimes some issues are just too painful to deal with at first. Only you will know when you are ready.
In the meantime, there is an excellent widows online support group called WayUp - link is here way-up.co.uk/. It’s an excellent site and the people on there are very supportive of each other. Everyone is at different stages of the grieving journey so there’s a wealth of experience on there - it may be the stepping stone you need towards some sort of counselling, or it may provide the ongoing support you need.
I can tell you from experience, the pain does lessen, you do adjust and you learn to live with the loss. The good memories return and bit by bit, you will enjoy life again.
Please talk to your sons and tell them how you feel and how much their behaviour hurts you, and encourage them to share their feelings with you. Hopefully you’ll find a way through together. Take care.?
