Please someone reply or I'll just have an anxiety attack. Is the feeling of having anxiety same as the feeling you have when you're scared? Help plsss I beg you

I'm currently living through a massive health scare with really scary symptoms. I am scared I might have an aneurysm due to my symptoms but despite that the doctor's don't think it's urgent. I have some test scheduled but I will have to wait weeks for some of them. I don't know how to get through this knowing I could die any moment. I live in constant terror ever since those symptoms started. I can't function. Can anyone here please help me with this??? I don't know what to do?

I’m on my period and o think my ocd feels a little worse today… I feel anxious and like something bad is about to happen, like I can’t move or talk cause I’ll freak out or snap and do something. Also I had a gronial response about an SA topic and I feel horrible, I’ve noticed that I do have these gronials as if I’m actually into that but idk if it can happen that you have the gronial and think “oh I’m horny, not about this but I am” is that possible? Idk how to say it… also I think I just want reassurance but I’m also scared…

i’m currently experiencing a panicky anxiety attack and i don’t know why. i’ve been on edge all day because of being scared to get sick, but right now, i know i’m not going to get sick but i’m just really panicked and cannot calm down. i’m currently listening to music that helps relax me with an icepack on my neck to help, but not much is happening. my sister and mom keep coming into my room and it’s only making it worse but i don’t know why. i just don’t want to talk or be around anyone right now. these kinds of episodes are worse than any other because i don’t know why i’m so scared. it just feels like it’s never going to go away.
