You can feel when it hits. That punch in the gut, heart breaking feeling of absolute dread. The thoughts of "I'm not good enough," "what if I fail" and "I want to give up." When these thoughts hit, it's hard to push them out of your mind. It doesn't matter if it's 3 in the afternoon or 1 in the morning. When the thoughts hit, you feel the blow.
And the thing is, the thoughts never really go away, do they? They're always in the back of your mind, waiting to rush up to the front of your brain and paralyze you with anxiety when you are least expecting it. This feeling can sometimes be indescribable and unimaginable if you haven't felt it firsthand. But it happens and it's real. Your heart pounds, your breathing gets a little shallow and you feel nauseous. You try to slow your breathing to prevent a full on panic attack, but sometimes the feeling just won't pass and you succumb to the devil that is anxiety.
You are not weak, though. You are STRONG. Your thoughts are the monsters under your bed who want to see you fail. But you have to know that you are stronger than them and you have the power to defeat this.
Having anxiety doesn't make you inadequate by any means. In fact, going through this on a daily basis, or at least a weekly basis, makes you so powerful because you simply know that the feeling will come and it is not a stranger. Even though it won't pass right away, eventually your breathing will slow and you will feel better.
But until then you just have to sit with yourself and believe with all your power that you will make it through this and you will become a stronger person because of it.
