Dealing with feelings about appearance

Assalamu alaikum. I've been thinking, why did Allah create unattractiveness when even Adam (AS) faced tests? All prophets were given beautiful looks, maybe so people would listen. I feel upset, like my destiny is to be alone because many sisters today prefer handsome or average-looking husbands over someone like me. I'm not even wealthy like some unattractive rich men who can marry anyone. What did we do to deserve this? I struggle with these thoughts and sometimes feel resentful. How can I face Allah with this in my heart? In Jannah, won't everyone be beautiful, making our worldly struggles seem pointless? It feels unfair, but I'm trying to understand.
