Hello there, I don’t get such mails very often but I’ll try my best to give you my opinion on this matter. You don’t necessarily have to follow my suggestions, it’s just some food for thought, yeah? :)
Well, first of all, I guess you’d have to acknowledge that there are areas in your life which might be “problematic” or are causing you/your loved ones around you some form of pain/worry.
Find out what those areas are and decide on how you should tackle them! Be firm with yourself and not waver after making a decision (i.e. don’t look back) Draw strength from those around you and this strength will help you to move forward :)
Coming from a Christian background, I’d suggest you to get some Godly advice from your mentors or church community to! :) Hope that this will help to steer you in the right direction in determining what a “better life” is!
