Hi I'm new to all this, any advice is welcome

Hi there, I am new to this community and BDSM in general.

I am curious about how to figure out what kind of sub I am- or where I land within the community in general.

I had one short-lived experience, and in that short time, they suggested I might be a little? But I'm not entirely sure what that all entails... There is so much information out there that it's overwhelming and confusing.

I guess some general information about me is that I am pretty anxious and can be childish, even in my friend group. Everyone sees me as the little sister of the group / bratty / gremlin <-- these are their words, not mine.

I struggle with making decisions and crave structure and routine, but it's something I struggle with putting into play myself and keeping. I have done some digging on the topic of little space, age regression, and all that, age dreamers, age play, and it's just getting more muddled and confusing, and to be frank, it's a bit complicated to understand...

And I am trying to understand myself better- trying to know where I fall in the community and genuinely trying to learn and understand the community as a whole.

Some more general information is that I do struggle with anxiety, PTSD, bipolar type 2 (which means I don't get extreme mania- but I have hypomania, which is just terrible depression, and I experience mania on a lesser scale- for me, my mania is more like- I feel hyperactive and have energy) I also have agoraphobia, and depression. I also know I am clingy, crave attention, and struggle when I don't receive attention and affection.

I recently got out of a very unhealthy living situation where my emotions were suppressed, so I'm going through a whiplash of understanding my feelings and emotions on a grand scale in my new and safe environment and I've noticed a shift in my personality ( it being childish ) - and I am exploring the concept- idea having a Dom to help with the things I crave and struggle to instill for myself.

So, in general, a lot of my questions start with - how do I figure out what fits me as a submissive? What are some things I need to know before starting or looking for a dynamic?
