I feel like im a failure in all i do
I look in the mirror and i dont like what i see
To me, it sounds like there are four things you need to do:
1. Believe in yourself. What are you good at? No Eeyore "I'm not good at anything" responses. Everyone's good at something. I svck at a LOT of things, but damned if I'm don't have a mind for essays, writing, and myth/folklore. Focus on that, build on it. Make yourself better. He'll, if you're really at a loss, LEARN how to do something. You may surprise yourself.
2. Exercise. Take care of your body. Do what you need to in order to like what you see in the mirror. If you don't like your appearance, there's always, ALWAYS a way to change it so it's at least tolerable(trust me, I'm speaking from experience). And if you were being metaphorical there, then it's even easier to change things up.
3. Get out of your comfort zone. The status quo is obviously not working for you, so why stay lurking around in it? I know it's easier said than done, but go on an adventure. Do something you haven't done before. Get yourself out there and meet new people.
4. Stop giving a [censored] what people think. Seriously. 99.9 percent of the people you see, you won't ever see again. What are they going to do if they think you're goofy looking or something? They aren't judge, jury, and executioner. They're people. Doing people things. And most of the time they're too absorbed in their own stuff and insecurities to care much about you. I know that sounds like BS, but its really true. All you need is that group of people who will be your friends, and someday maybe that special someone(who won't give a [censored] about stupid superficialities). Everyone else? They can [censored] right off if they don't like you. The sooner you understand this, the better.
I hope some of that helped.
