My therapist told me that when I'm spiraling down into negative thoughts, to use calming breaths as like a speed bump so I don't think about things so irrationally. I'm trying this "thought stopping" technique but I can just feel myself spiraling down this path of all these thoughts of how I'm so unloved. 

I was supposed to go on a date with someone I really thought I was getting along with, but he flaked on me and told me that he ended up having to cover someone else's shift at work. I told him that it was fine, it the best, most understanding way possible and now he hasn't texted me since and has viewed all the texts and I just feel like I ruin every good thing that comes in my life. Like, I'll never be fucking loved, I had a good thing going texting this guy and like, now he just stopped talking to me like what the fuck did I do wrong. 

Then thinking about all of that turns into thoughts like, about how alone I am and how it's my fault nothing works out for me in life and I'm just one big failure, etc. I really don't want these thoughts to get any worse, and I feel them creeping up and I'm essentially about to have an anxiety attack just writing all of this out. I feel it. 

Help me come up with a technique to stop myself into delving into these inevitable suicidal thoughts, because I know they're coming. 

I feel so embarrassing writing all of this out but I really just don't know what to do at this point and my next therapy meeting isn't until Tuesday.
