Frustration is often rooted in an unfulfilled expectation you’ve allowed to grow bigger than your peace. You have options to deal with this. You can use your remaining strength to stuff the negative thoughts and emotions down. You can use your skills and experience to try and manipulate the outcome you want. You can let frustration expand into full-blown anger, resentment, and bitterness until they rewrite your identity.
Or, you can grow your peace again. Focus on every good thing in your life until the joyful thankfulness it brings overwhelms the negativity. Pray and listen for who God wants to be for you right now, until you have all the grace and wisdom you need to productively deal with difficult people and situations. Give God every insecure, stressful expectation until the only expectation you have left is of encountering his goodness every day, no matter what’s in front of you.
