i really need your guys' help...

Try not to make bad decisions....but honestly, I've made several in the past week. We all have bad days/weeks, so just try not to let that happen again. And if your best دوستوں hate آپ for how آپ are changing, then that's their problem. They should appreciate آپ for who آپ are, not hate you. But sometimes they just act that way, even when they appreciate آپ for who آپ are. So don't let that bother you.

Listen to music.
As the old saying goes..

Just focus on what makes آپ happy =3

Follow your morals. Do what آپ know is best.
Every pain and stress is difficult, and hard to overcome. But it always subsides, and the storm always passes, and you're always stronger when it does.
Get your parents to trust them, دکھائیں them that آپ can be trusted and that آپ learned from your mistakes and bad decisions. If your دوستوں leave آپ for it, then so be it. If they leave your for changing in the first place rather than supporting you, then they aren't what آپ need to begin with. It may be lonesome, but being alone and having strength in yourself is far better than being with دوستوں who beat آپ down and feel worthless.
It's hard, it's difficult, and it's hell, I know. But آپ can make it out of this, and آپ will get stronger from this if آپ let yourself.
