Go read @X_Austin_X 's project talking about this and go follow his studio for this, Project: Reach Out
You may feel that no one understands or notices your pain, but believe me a lot of people do notice and care they just don't know how to comfort you or they don't want you to feel pressured into telling them anything you don't want to share, so they choose to stay silent because they believe it's better for you. Just know there are so many people who care about you and want you to get out of any situation you happen to be in. And if you ever need their help don't be afraid to reach out they'll do anything to help you even if they don't show it that much.
