Feeling overwhelmed by grief and anxiety. Looking for ways to cope

I’ve been struggling with a heavy sense of grief lately, and it’s combined with terrible anxiety that I can’t seem to shake. Even though it’s been a little while, I keep getting pulled back into memories. Some are good and the other ones are painful. It’s like i can feel them physically, like I’m re living certain moments. You know ? Like hearing the same music, sensing the same environments, and remembering my thoughts at those exact times. It’s exhausting as hell :( On top of that, my mind keeps going on about the “what ifs” and comparisons. I grieve about the connections I cared about deeply, and about never finding that closeness again. About being alone in the future. Even when I try to calm myself, certain triggers like a memory, a song, or a random thought brings the anxiety back instantly. Sometimes, the grief itself feels manageable, but the panic and thoughts make it really hard for me to think clearly or focus on anything else. I feel like I’m carrying all this weight. I know that some of this is normal in grief, but I want to find ways to process it without letting it take over my life. How do y’all cope with grief that triggers intense anxiety ? I would appreciate any advice or help that might help me handle this better. Thank you
