Asalaam
Never regret the good you do and never wish to be in sin. No matter how appealing sin may seem there is always some form of deviance with any sin having the possibility to take you away from Allah. It is the favour of Allah that he has safeguarded your chastity and kept you steadfast, the effect of sin could have easily distracted you from your studies, left you with no job and no prospects. Wishing and regretting will lead to frustration to anger to not letting you having peace in life wishing that your brothers who previously sinned are destroyed. You are for yourself, if you make the enjoyment of youth your objective no matter how much enjoyment you took it will end and leave you in nostalgia, wishing or regret. Make deen your objective and try to find ways to learn and excel in the many areas. More can be elaborated if you change the mentality of frustration over what seems like loss in the world and change to hope over improving YOURSELF.

This is from experience you need to change your outlook its not your situation that is the problem.
