I feel guilty after doing a compulsion

Less than a year ago, I had a very big anxiety flare up to the point that I felt as though I needed to report to the police / harm myself. I ended up leaving an anonymous tip at the police hotline about something that I know I didn’t even do but everything told me I had to or else I will go to jail. And similarly after that I called the help line and explained I had unwanted intrusive thoughts and I didn’t think I deserved to live for having those thoughts. After these many months and working with my therapist, I’ve been able to feel a lot less anxious around this topic and now I’m getting lots of anxiety about what I did that time when I was so anxious. I gave in to my compulsions and confessed for stuff that I know sounds bad saying out loud but only certain people will understand I would never do. So now I’m just looking for someone to relate and perhaps let me know that I don’t have anything to worry about? I know it’s bad to seek reassurance but I’m not sure where to go. And I’m worried I’m going to keep incriminating myself.

Why did the compulsion/test people told me I did felt very wanted in the moment. But then I regret it now and afterwards. Still a compulsion, correct? It just didn't feel like a compulsion, but then again I don't know what those feel like

cause immense guilt when receiving gifts? Or when someone is nice to you, the guilt just floods every vein of your existence. I feel so awful :( awful about my compulsions, about some of my thoughts, about who OCD has made me. My boyfriend just gifted me something, and I have such a heavy feeling in my chest. Worst part is: when I’m not feeling guilty I’m spiraling over that gift was enough, if it could’ve been “better.” I feel like an idiot. I don’t understand why I’m like this
