Adam,
We all have days where someone says something that gets under our skin, something that normally we could handle. Use it as a reminder to not be that kind of person. Once you accept that happiness comes from within, the external forces have less impact.
You do what you do because you enjoy it. It is fun to share what you enjoy with like-minded people. Apparently, not everyone viewing your social media page can appreciate this. Set your own goals and standards for accomplishment and don't settle for someone else's idea of success.
Don't let it get you down and do not let it stop you from sharing your interests with others. If anything, concentrate some of your time and energy on establishing friendships with people that will be supportive and that can find joy in sharing your life and your accomplishments.
I tried to remember what life was like at 26, but my current fat and decrepid self kept blocking my recalling that time of my life; probably to save me from a bout of depression! LOL!
