I feel extreme guilt right now

I just saw a post on here that reminded me of something I did, or thought I did, nearly 12 years ago. I don’t know exactly when, but my OCD just latched onto it. I don’t even know if the memory is real. I’m freaking out. I was just a kid. Why am I feeling so guilty right now?

I woke up very late today because my son kept me up all night because he is teething so I didn’t fully wake up until 6am. These past months have been crippling because of my ocd, depression and anxiety. So crippling to the point I have been terrified to leave my bed. Because I haven’t been leaving the room often I am starting to come off as lazy to my mother in law and I have been slacking on helping around the house. My mother in law has surgery on Tuesday and needs us to help out more. I got up to do the dishes the other day and had to stop because I was having a flare up and felt like I was going to over heat from anxiety. I laid down and never finished the dishes. Today she came home really mad at my husband and I because we haven’t been helping and the guilt is eating me alive. I want to apologize but I don’t want to bring up how I have been feeling because I don’t want it to come off as an excuse. I don’t want this to lead to a point where I’m suffering because of it and I don’t want it to ruin her perception of me. I just feel awful that I’m letting this take over my life. Moments like this make me feel useless and I lose hope of ever getting better. what if I never get better. She does so much for me and I’m letting her down💔

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
