is this normal ?

the thoughts that have been making me super anxious recently is every-time I’m around someone im happy with my mind is like “they will miss you” or “they will wonder why you did it when your always happy” it’s eating me i hate it. i’m tired of this theme, it’s been on and off for three years. but it makes me more anxious now the it does before. please share tips

So recently my mind is trying to make me feel like I accept the thoughts, like I'm ok with for example loving X person. After I get a thought like that and I realize it I get anxious and, like right now, I cry for 1 hour+ on the bathroom floor. I feel exhausted and I want to know if I'm the only one having this.

I’ve been perturbed for a couple of months now with incessant thoughts about aging and dying. I really am not sure what to do. This feels like other OCD themes, but also really different, because this time, what I’m afraid of is sure to happen. I will either die, or age and then die. It’s been so difficult to enjoy anything lately. I just want to pull a blanket over my head and wait until death comes. Has anyone else felt this way? I feel quite alone. I am trying to enjoy life, but I just remember that it will all be gone in a flash. Nothing really seems to help me feel better. The only escape I have is in my dreams where I can fantasize about never aging or dying. Or at least being able to rewind the clock to have more time.
