:/ in Bittersweet

Well my manager gave me an update on the possible new position.
The store manager agrees im the best candidate. That both my counterparts up front will be livid i get this job over them. But that im the person who will do the best at it.
Downside… looks like its going to be months before they put the position into play. Im really bummed. It would be monday through friday 7 am to 4. And float wherever im needed if we are over staffed, Do stocking ect.
But im really disappointed that its going to take months. But not only that, im not likely to get a raise. I didnt when i went from part time to full time. Would you be a book keeper and cashier and floater for 12 bucks an hour. Am i under selling myself or are my lack of skills.
The two people i trained this week say im an amazing trainer. That im understanding and patient. But fuck… Im just exhausted.
Maybe next week will be better… I mean if i stick with it i move up and possibly have a chance to move into the corporate end, business end. If i quit i have to find another job. And am i better off? I still feel like i have no skills here. Its almost been 6 months now. And i have no chances to get raises or move anywhere other then adding on responsibility. It makes me wonder is it really worth minimum wage.
