Finances and friendship

Many of my friends are very successful and have built some great lives for themselves. I'm so happy for them and they deserve their luxuries. I'm not jealous in any way and they are more than generous buying our kid gifts and always sending us beautiful cards in the mail with adorable family portraits. We are a military family and living off one income so many of the things I want to do, like send their children gifts and go visit them, and just be financially comfortable haven't always been the option for us. I often have to turn down events or trips. Also realizing that we probably can't even afford to move back to where they all live since property has gone up in our state has me super depressed. Does anyone ever feel inadequate or like they constantly have to tell friends they're broke? It's really embarrassing and we are comfortable I definitely don't feel "broke" but we are living paycheck to paycheck while we pay off debts. I'm thankful for what I have but sometimes I just always feel like the odd one out.
