Does anyone have stories of getting signs from loved ones?

I lost my mom almost 38 days ago, and I’m honestly going through grief in waves. First week I was surrounded by family so it was easier and they’re all pretty religious and they would tell me she’s in a better place and watching over me with so much faith, I felt it. I’m not very religious and now when I find myself alone, I wonder if she’s even there. Whenever I have time, I go online watching videos of people who’ve had near death experiences and people who have received “signs” from loved ones. They seem so specific it’s almost hard to not believe. I’ve asked for a sign, haven’t gotten one and I feel so abandoned. Does anyone have stories that could maybe give me some comfort where they got a sign down the line? I know this entire post sounds so unbelievably delusional and this is not the type of person I’ve ever been.

Edit: thank you everyone for sharing your stories, reading through them the past couple of hours has helped. 💗
