It takes great maturity to handle situations like this with such grace. You are a true friend to have been genuinely happy and excited for your closest friends' weddings. It is also admirable how you have reflected on your own feelings and assessed yourself honestly. Your confidence that your friendship will endure even through life changes is inspiring. Remember, everyone's journey is different, and it is important to focus on your own path and not compare it to others. Keep being true to yourself and stay positive, great things are yet to come for you too!
