You stated yourself, You are not too well known in the community since your 5 month parting, And because of that a lot of new players and staff do not know you too well, if not at all. I also have not seen you on the server as much, Yes your name pops up every now and then but I've never seen you doing much RP. If you just came back or recently did, Then I don't think you should put up a mod application just yet. I'd say give it at LEAST 2 weeks, But through out the 2 weeks you would have to be super active and get well known. Otherwise I'd just recommend a month since you stated you have been having some sad times recently, to prevent stress just take it easy.
