I agree with most of the commenters here, except I didn't even think about it until my therapist brought it up. Once we started dwelling into my childhood at depth, she asked to see a photo of me when I was around 3/4. I didn't think anything of it at the time. But since then, every time I examine a photo of me at that age, I feel really, really bitter. It just feels like a childhood wasted. I see the smile or the love from whatever family member I was around, and I feel so dead inside - yet so upset by it at the same time.
But then again, I don't know, maybe that's part of the point, to trigger a certain feeling I should be working through. It's certainly a feeling a didn't know before, and as awful as it is, maybe it's leading me closer to dealing with something I need to.
