Struggling with the 4th of July Away from Family

It's my first 4th being away from my family and I'm struggling. I'm still early in the process of making sense of sensations and what may be triggers and tracing it all back to cause. I have my mental health team, with meds and therapy in addition to learned skills, grounding meditation, keeping busy, etc. Instinct has it to talk to my mother, but she has invalidated me, plus, she'll just tell me I only have positive memories of the 4th (which is what I recall currently) but I have also been unearthing other horrible memories, which she would also not believe. I haven't had any experience with violence directly in that sense, so I'm still out on what's triggering me. Just would be nice to have some exchange and maybe talk to someone who understands what I might be going through. TIA
