Grieving my daughters loss. Social isolation and depression

It has been a little over 2 months since our daughter decided to end her life. I am still devastated and even though I'm getting professional help to cope with it, the sadness and images come every night. Waking up also brings a knot of reality in the pit of your stomach and you wish it was not real. And to control the mind from going into the areas of regret, self blame of things you could have done, the "should've, would'ves, and could'ves" just destroys me each day. I am not sure how to regain any focus. I feel like I go thru the motions each day but it's like I'm not really there. Vertigo, are my feet actually touching the floor? Like youre a shell of yourself. She had so much to live for. She was truly an old soul trapped in a young girls body. My girl was a straight A top honor student, who aced an associates degree in law with a 100%. A very artistic, gifted child. Very mature for her age of 20. She was my one true blessing and my main focus every day, along with being my only child.
I too have trouble even going anywhere in town. Everything brings a memory. Anyone just simply see something in a shopping store and start to break down into tears? This happens constantly for me. Memories, things I see I know she would like. This is my new normal and I don't know how to deal with it. I have taken to therapy and have been trying to tap into any support group I can locally. My family has been very supportive and friends too but there are times you feel as though you are tapping out their energy. It helps when talking to people but my fears are that they will become overextended in how much they can give. The pain is an energy transfer. It affects everyone, like ripples in a pond when a stone is thrown in. I am very open to suggestions from anyone on something that will help. The grief comes in waves and when it's raining down on you it's hard to know what to do next. My daughter meant everything to me and I feel like all focus I have is gone. How do others deal when the waves hit? I need to know of something that will help.

She was suffering from severe social anxiety and depression brought on simply by 4 years of isolation doing remote schooling. Due to her sensitivities she could not have certain medicines or vaccines, she was alot like me in this respect. She was not allowed to attend the final two years of high school or even the college due to mandates. She started to recede into a shell and didn't want to go anywheres even when she could. I am just beside myself with grief. I miss her so much it honestly hurts my heart.
