Welcome to SR. I advise spending a few hours reading around on this forum and you will see that your problem is quite common. Withdrawals, boredom, not feeling well, sense of insecurity, yet we keep doing it. I can tell you with confidence that those things will go away with sustained sobriety. The early days our minds and bodies are in a transition, from being numb to being sober and present in our lives. That transition is sometimes uncomfortable, but gets much better with time. You are wise to catch this at a young age, you won't regret living a sober life.
