Now you've come to a realization where the thing that makes you unhappy with your life all this time is that because you always put someone before you. You put so much effort to make them feel better with theirselves, while you, on the other hand, you forgot how much time, energy and money that you have invested on them. Do they even give you an appreciation, simply by saying "thank you", maybe? no? Well it's time for you to wake up. It's okay to be selfish in the way that "oh, I have gone this far. What did I do to myself that I didn't even appreciate it?" Today, don't just say sorry to others, be sorry to yourself and appreciate yourself for all the things you've achieved.
