Younger self: Assure him that there will be better days to come. Teach him a few techniques for self-defence as well and hope his হৃদয় will be trained enough to express himself when needed.
Future self: Remind him that he had lived through better days at some point. It still is possible. Take a break together to do things we প্রণয় in general !!!!
Just go full on goth. Right away, don't wait just go full on goth. And be আরো persistent in begging to see টি.এ.টি.ইউ. in সঙ্গীতানুষ্ঠান because they'll disband দ্বারা the time you're 'old enough'.

To my younger self; আপনি may be a bit of a crybaby currently, but don't feel ashamed to let your emotions out. One day, you'll end up where I am now haha :) Fight off those bullies! Don't do it physically though- Don't worry about your weight so much, it makes you, you~
Future; Hello me, I don't know where আপনি are now, but I hope আপনি are doing good. Although আপনি might be struggling with something, don't be scared to speak to someone about it. Be yourself, and don't try to become someone আপনি can't :D
