Funeral soon, I don't know how to cope

It is the memorial service of my beloved partner next week, he took his life exactly three weeks ago now. I’m 22 years old, I have never dealt with this level of loss and pain, I feel so overwhelmed with everything in my life. I am struggling to find joy or meaning in the things I do, he should be here with me. I just miss him so desperately I am still in such utter shock. my whole life has just suddenly changed in such an awful way. Any similar stories or words would be lovely to hear <3

Dear Blake7 you are so very young to be going through all of this. I lost my partner suddenly 22 weeks ago and like you my whole life was altered forever in an instant.
We are interring some of his ashes tomorrow and I feel more anxious about that than the actual funeral. I think I was probably still in shock then, as you will be now. Everything seems more real now.
Don’t expect anything of yourself at the moment. Just try and get through each hour and each day. Try and eat something and rest when you can.
Keep posting on here. Everyone understands and no one judges. It’s been a lifeline for me. Take care
