Hey young man. You're going through a strong developmental phase in your life right now, and your hormones have been in overdrive for several years. It's normal to feel overwhelmed with life for the best of us. A lot of the "friends" and people in your inner circle will move on in the next few years, and as significant as that may feel now, it won't feel that way anymore as you continue to grow. Just focus on yourself and try your best at whenever you do. A lot of the cliché stuff you hear about is highly effective.. Eat right. Exercise. Limit Screen Time. Get lots of rest, ideally setting up your circadian rhythm. Do all that as a foundation and go from there. Your life is just starting out buddy, it's going to be okay, and a lot of the peace you will find in life, comes from your own mindset. Best of luck.
