Your feelings matter, and if you feel as though you can't open to anyone, you can open up here. Feel free to use this website as a journal of sorts.
Also, take a look deep down and ask yourself if those negative things you said about yourself are actually true, or simply things you've convinced yourself to be. Surely you have things to offer to this world. Surely you have things you enjoy doing and talking about.
Try to find places near you where you can volunteer (helping animal shelters, that sort of thing). It'll make you get out of your house, feel useful, and meet new people.
