When experiencing anxiety, I presume a level of scheming that's outright diabolical behind everyone's behavior and I paint the gloomiest possible narratives by connecting dots in my head that have no place being in relation to each other. Recently becoming aware of this fact, I encouraged myself to do the opposite - assume positive intent wherever possible. It worked, but only in that I recognized the futility of either method. 

There is no limit to the negative or positive explanations you can give yourself, meaning the outcome is completely subjective and has no bearing on the reality of the situation. So stop letting your mind spin either narrative. The only solution, however hard this is to achieve, is to stop dwelling on it at all. 

How might this actually play out in life? Well you can start by taking people at face value. Would it be legitimately devastating to place all your trust in someone and then have them turn around and stab you in the back? Without a doubt, but only for so long until one day you can pick yourself up and stand even taller. But to assume the worst of everyone, on the other hand, that's how you sabotage every relationship before it ever even begins. And then when things fall apart, you're only further engrained in your ways. You tell yourself that this is only proof of your right to worry, that you were right about their malintent all along. You will never break the cycle this way. 

So just submit. Just ride the wave and roll with the punches and love when and wherever you can. Weed may help with this.

(this doesnt mean just put trust in everybody you see, it means taking them at face value when they show themselves to be worthwhile)
