9 Months into my weight loss journey and confused

Options
I'm looking for some advice. I'm 9 mos into my weight loss journey, I've lost 60 lbs, but I'm not sure what my goal weight should be. I'm 5'4 and 41 years old. I've looked at all kinds of sites for advice and so far my range is anywhere from 108 - 145. Currently I'm at 158 and I'm thinking about trying to get to 145. All my life the insurance company guidelines have said that I should weigh 135, but right now I can almost fit into size 8 clothing at my current weight which seems small enough to me. I just don't know what to go by or who to beleive anymore. Any suggestions out there?
