What to do with an emotionally unavailable/supportive girlfriend?

Today I was very down because it is the one-year anniversary of a something traumatic that happened in my professional life. It took several months to cope with it and I am okay now however there are moments when I get down about everything that happened. So I text to my girlfriend that I need a hug. I recap things and she says, sorry and sent me a high five and a strong arm emoji. I know she cares about me however it feels so cold and unsupportive. It took a lot for me to even ask her for a hug because I haven't done that before but I needed some comforting from her. I did not reply to her emojis and it has been a few hours and nothing more. In general, I feel she is emotionally unavailable to me (not the first time) when I am available to her. It feels very lonely and like abandonment of some type. Thoughts?
