While depression makes you feel numb, anxiety makes you feel way too much, more than your mind can comprehend.
Anxiety's the reason you lay awake at 3 am, worrying about some thing you may have done two years ago. Anxiety is why you have to prepare yourself two hours in advance before you go out to meet people, even sometimes friends. It is why you ignore calls, and prefer to answer texts, so that you have a few minutes to think before answering. It is the reason that you wait beside your phone, waiting for that one text you need to know that everything is okay. Anxiety makes you believe you're alone in the world, and you don't really deserve love. As a consequence, you desperately want to please people and are terrified of confrontations. It makes you believe that people are temporary, and nothing you do can make them stay, because you're simply not worth it.
To these people, I just want to say: Don't give up hope. You are beautiful and brave and needed. You are some of the best people, as you would never let people suffer what you do. You take their pain, never worrying about your own.
You will have a better life, maybe not tomorrow, not in a week, but eventually. No one has the power to take anything from you that you don't give them. So, keep the power, and believe in the light. For now, just concentrate on taking it one day at a time, waking up in the morning, and going through the day. Then, a day will come when it will be easier to look forward to tomorrow, when there will be no dread, just anticipation. It will come. It has to.
