I bet a lot more people care than you realize. from what I have experienced, people just don't know how to reach out and let you know that they are concerned or thinking about you. life can seem overwhelming and useless at times, but I have learned, just like you said, nobody will probably respond to this post, nobody ever responds to my posts either, I have learned that I have nobody to count on but myself. I had to become important to myself and learn to live for myself and how to comfort myself. in doing that, I noticed I became important to other people. the more I cared about me, the more others cared about me as well. so be somebody important to yourself and take care.
