You're not alone bro, amphetamine withdrawal is a bitch. Nothing is gonna heal it except time. I start to feel like I'm returning to reality after 4 days sober. Don't feel bad you're not responding to your text messages. Don't feel bad the only time you're motivated to move around is when you're going to the fridge. Don't feel bad your entire world view is warped and you're feeling cynical about everything. It's just temporary and it will pass. Go to school/work, put in the minimal amount of effort required to get by, go home, eat, eat, eat, lay in bed, and just ride it out.
