If happiness is unattainable, what can I aspire to?

I’ve never been happy. I always have high hopes and constantly let down.

When people hang out with me it’s like we never get to do anything exciting. We usually sit and have coffee, but with other friends they check out museums, go hiking, etc (basically things I’d like to do but I never get invited to).

I just went to visit an old friend. He slept all day and it was all about his boyfriend (who didn’t even care to get to know me). I caught an early flight “due to weather” but in reality if I wanted to bedrot, I could do that on my own.

I’m on the plane sobbing. I was so excited. I’m not a good dresser but I picked out an outfit I was really proud of but never got to wear it.

I want to be excited about life but constantly let down. I think my expectations are too high for someone like me. What’s the alternative to happiness? Acceptance?
