Welcome to the Steem Network. This community is not as simple as Facebook, but it's also not as complicated as it seems at first. The main thing is to keep your passwords safe... and written down in at least two different places. When in doubt, don't enter your keys in a site without asking around if it's safe.
I wish you all the best. May you be happy in here.
PS: I've find your post because @bengy featured you in his entry for the Pay It Forward Contest
I'd like to invite you to participate in My Art Curation Initiative #7
