Good morning ARDG
I’m not sure if you’ve already been to see your GP but maybe a chat might help. Sometimes a short course of anti depressants can help but I’m sure your GP would be able to give you some support anyway. I know that a lot of places are reluctant to offer bereavement counselling so early on but my son paid to see a bereavement counsellor and really felt it beneficial. Have you thought about some alternative therapies for yourself? Reflexology maybe?
I hope you’re doing OK. There are lots of people here for you x
