Anxiety and my experience. in Maze of my mind

So my legs are literally shaking, I was feeling much worse few seconds before but now with earplugs in and listening to Believer by Imagine dragons I feel better, although the lingering feeling is still here. Sometimes I question as to what if I don’t really have anxiety? What if I am just making it up in my mind and just overreacting? What it was never there? Many times I was tempted to believe that in self-loathing, but other times I get some evidence that it is real, such as just NOW.
One thing you must know about someone who goes through anxiety is that normal everyday thing, common chores, simple tasks can be hard and challenging, it may not be the same as laying in bed silently as in depression but bustling about the kitchen and checking everything thrice, or walking real fast when going to your room, or pacing in the room at night, but it’s not only restlessness.
Sometimes it’s worse and that is when your BODY COLLAPSES IN YOURSELF. You can’t move even if you urge yourself to, you can’t lift your hand no matter how much you will it to, and all your emotions go on a roller coaster inside your body, its like your body is a CAGE FOR THUNDERING DEVASTATION, and since it can’t come outside it kills you inside.
And whenever it comes, it leaves you exhausted behind, incapable of doing anything for a few minutes. Sometimes it is the tingling sensation in the legs, as if they would do when your are nervous before your school announces the winners of some competition, but it doesn’t stop there, because it quickly escalates to cramps in your legs, and you feel like you want to massage them or curl up and hold them, at least that is what happens with my limbs. Both hands and legs. And the breath, oh goodness it becomes hard to breathe but it’s been so long for me that I am now used to not getting full oxygen during this time, and the sensation on your head, as if someone has grabbed your soul by your head and sucking it out. It’s awful. It’s scary. And it happens to so many. I feel as if the reason I let my situation get out of hand is because I believed that I didn’t have anxiety, I felt like as if I was pretending with myself, as if I was making it up.... So I never had the courage to pursue help. One part was also this that I felt I can deal with this myself, that I was strong enough.
But if YOU or anyone you know is going through it, please TALK. GET HELP FOR YOURSELF/THEM. It’s no good keeping it all inside. I was lucky to have support from my family(sometimes they are strict though), but everyone may not be. So please don’t waste more time. Talk. Talk to me. I am HERE. For you.
