Detailed Answer:
Hello XXXX, Welcome to HCM,
I've gone through your query in details and understand your concern,

It seems like a vicious circle of social pressure which is apparently causing all these stress, thus making you to seek help of alcohol in the end..

Please refrain yourself from alcohol, as when influenced by stress and other pressure situation, it often indulges in to binge drinking and several other adverse effects..

Yes, the shift work schedule is definitely one of the culprit here..

Your too young, and I'd always advice lifestyle modification prior to any medications..

You need to sleep properly (~8 hr per day), so night time prior to bed, I'd recommend a cold shower, half an hour of meditation with soothing music, try it, you can google for training video lesson for this before hand..

Make sure to sleep in a completely dark room devoid of any noise..

Try not to take any tea/coffee for at least 3 hrs prior to bed(preferable bed time 11 pm-7 am- practice it, it'll be worthwhile)..

Early morning go out for a light jogging session, you'll be feeling much better and refreshed if maintained in daily basis..

Keep your mind pre-occupaied, we can't bring back the past, but we can always improve the future by doing good at present- always remember this.. stressing and fatiguing yourself over all these issues will only make you unhappy at the end of the day, so don't think about them so much..

Do at your best, give your perfect effort and you'll be rewarded in the long run, but thinking about it day in and day out will only impact your personal well being..

Try to indulge in your favorite hobbies/activities, keep your self busy so that all these thoughts don't even get a chance to pop-in your mind..

Try this for a week and let me know how you stay..

If despite all these, there's no significant benefit observed, then medications like MELATONIN can be initiated in low dosage (please don't buy over the counter sedatives, as they're not only prone for more harm but also abuse potential)..

Do let me know if there's any further queries.

Take Care
Kind Regards
