Welcome, you will find the forum helpful.

Try not to be overwhelmed.

I haven't decided how best I like to read the forum yet.
I think I like being subscribed to a few threads best, but I still often scroll through news posts looking for things that pique my interest.

If I were you I would definetely start a journal so that when you make buddies they can check in on you.

Also I know in the exercise forum there are threads about Curves, you could join one of those threads and make support buddies there.

Under countdowns and challenges you will likely find a challenge or a buddy with similar stats or interests as you have.
You can even start a thread describing the kind of buddy you are looking for and find some support that way.

Good luck and happy LCing.
