✾ It is not your job to fix you. That's God's division. Your job is to stay as humble and malleable as you can, and beyond that to entrust everything to God. Your job is Micah 6:8.
✾ Try to fill your mind with good, affirming, life-giving thoughts. For me, this may look like spending a little less time on places like Pinterest or YouTube (where I am easily drawn into comparison or other traps) and a little more time reading and rereading authors who encourage me (like Kayla Aimee) and whose words might begin to soak into my soul with the truth of who I am as a beloved daughter of God rather than feeding my insecurities or misconceptions of who I have made myself out to be.
This can't become a legalistic exercise, though, or it will undo whatever good God is trying to accomplish through it.
✾ Please do not allow either Satan or you yourself to trick you into bludgeoning yourself with guilt and should's and ought's over things that are completely and objectively amoral. (For instance: If you are on a vacation and you decide you kind of want to live in your pajamas most days, do not make that into some sort of 'should or should not' situation. Chill.)
✾ Again, don't make this into a legalistic thing (again, don't make this into a legalistic thing), but maybe try reaching for something other than a screen every single time you're free. Try reading, or knitting, or crocheting, or (*gag*) exercising (I don't like it any more than you do), or crafting, or playing the piano or some other instrument, or singing, or drawing, or boxing, or playing games with a family member, or letter-writing (maybe to relatives or friends you haven't seen in a while). (This video has some good thoughts on it--although, again, DO NOT MAKE THIS INTO A LEGALISTIC THING.)
✾ Don't compare what your individual journey to a particular goal looks like to someone else's individual journey to a similar goal. (One of the things I've struggled with in this is comparing where I am in my writing journey to various online friends.)
✾ Matthew 6:25-34. Really try to meditate on that when you become worried about money or your future or 'adulting.' (And btw, if you ever are stressing about those particular things, know that I'm in that with you and I understand and I struggle with all that too sometimes. It can be scary, and it's okay to be scared about it; but think about how many people relatively successfully navigate that transition into responsible and independent adulthood ALL THE TIME. More than that, try to think about those verses. Believe you me, I'm pretty sure I've worried about most possible "but what if this happens" contingencies, but God keeps bringing me back to that passage. Trust.)
✾ " . . . peace at all times and in every way." ~ 2 Thessalonians 3:16
