Anxiety and crying days

Hi!! Sorry if I dont write good in English. Im gonna try to explain myself.

i feel so anxious about my future, in my work I feel like Im not good enough, this happens a lot with my boyfriend. Hes the most cute man. And I love him sooo much. But Im afraid hes going to find someone more cute, more beautiful, more intelligent. When I say goodbye to him, I feel sad, I feel like Im overwhelmed him with this anxiety problem. I want so bad to live with him now, but my salary its not enough. So I want to quit my job (we work together) and look for something better, he have a year in our job and I have 4 so I think its better for me to move one but I want that happens right now, nd I think thats whats make me feel so anxious, mi heartbeat turns fast like in a second. In my work y feel so sad and not enough, i have this ideas in my mind and i cry, and no one notices, but I have my eyes which tears, am I wrong? What happen? I dont know why you feel like this

thank you so much 💕❤️
