At the cost of sounding cliche, time heals all wounds.
Chill with people that make you happy, try to be around big crowds and try not to blaze (depending on the high you get) and drink too much, you're trying to make yourself better, not add a bad habit.
I ain't gonna lie to you man, it's gonna be hard for the first little while, and I really recommend staying away from relationships for a good year, at the least, even if the perfect girl comes along, keep her as a friend, you'll become more irresistible in her eyes. Take this time to improve yourself, and as corny as this may sound, learn to love yourself and be comfortable in your own skin, the girls LOVE that.
