I need help.

Okay I might sound crazy and I need alittle advice. Recently I took off work for a month to go visit Europe. I left being on very good terms with my work friends. They all said they loved me and they’ll miss me etc. They also usually text. Last time I left on a long vacation they would occasionally reach out to me, like my stories, etc. This time around, everything was normal for the first week. They liked my stories and we texted briefly. Now…. A week or so later, it’s dead silent on their end. They haven’t texted. They view my stories but they don’t like them. (I’m not saying they have to but it’s normal for them to do that). I can’t help but think something has been said about me that’s negative. Or they’re mad at me for maybe the one time I talked about them years ago in a slightly negative way because I was venting. (But doesn’t everyone do that at some point?) And I know it’s not nice to hear that a friend said something about you when it comes through a rumor. But that’s all I could think of. Maybe there is a lie being said or misconstrued. Or maybe I’m not that important for them like I thought I was. Or maybe it isn’t that deep? I sound legit insane right now because I feel like it shouldn’t be a big deal but every day I’m waking with anxiety. I feel so down and blue and any time I post I’m anxiously waiting to see if they saw and liked my story. If they didn’t like it but saw it, it just confirms my fear that they’re upset with me. Which devastates me because they’re close friends and they are my community back home. I work full time so I see them daily and we would always hang out. Now I feel like they all are over me and like I did something wrong but I just don’t know what and I’m so sad and anxious and I feel so dumb for even feeling this way because I can identify that I’m having a spiral but I have no idea how to stop it. I’m trying. I won’t reach out and ask them because that would just make my ocd worse. So I’m posting here. Does anyone have any thoughts or ideas on how to help me overcome this with out seeking validation from them? What are your overall thoughts and what techniques or exercises would you recommend for me so that I can stop letting this consume me? Thank you in advance if you are still reading.
