Worried about missing my anxiety medication

Hi everyone, I'm in a bit of a predicament with my anxiety medication. I'm going on a trip soon and just realized I only have enough pills left for today. My next refill isn't for another 10 days or so. I take 100mg daily and I'm really concerned about potential withdrawal symptoms while I'm away. Does anyone have advice on how to manage this situation or minimize withdrawals? I won't be able to contact my doctor until I get back on the 5th. I'd really appreciate any tips or support. Thanks in advance!
