There is always light at the end of the tunnel. Please hold on a little longer and you'll reach it. Please know that there are people who love and care for you and are willing to help you through it. You never have to go through it alone. And even if you feel like you have no one, you have us. We care about you completely and many of us are willing to talk you through it and support you through it, even if we can't be with you in person.
Don't ever give up, hold on tight to where you're heading, and remember that no one's opinion matters. The way you see yourself is what matters and those people won't always be in your life. Life is stressful, it's a part of the package but you have to push on through. It will get better. You just need to wait it out. It isn't over yet, don't let your mind trick you into thinking that it is.
Anyone who doesn't want to see you become the best version of yourself needs to be cut out of your life. If they're bringing you down and telling you that you aren't worthy, they aren't worthy of your time. They don't matter. What matters is yourself and what you think about yourself. The job of some people is to bring you down even when you don't realize it. These people are obstacles and once you figure out how to overcome those, you're set.
Even if you can't live for yourself, live for those that love you. We cannot bare to lose you and it hurts more than anything. Please, just hold on, even if it's by a thread. That thread will get thicker and stronger and turn into a rope strong enough to lift you back up. All you have to do is hold on.
