relationship anxiety

don't knw if its because I'm PMS'ing or not but, my bf of almost a yr has been going thru some real tough times w jobs, family, rent etc. I vented to a coworker about it and basically she told me since this is my first serious relationship that it won't work out and to "not hold my breath", even seems like my parents sometimes don't want me to "close myself off to any options". I'm 22 and yes this is my first relationship and yes things are stressful and not easy right now but I have never questioned his love for me. my coworker really got to me and I literally bawled my eyes out for 2 hrs bc I don't wanna lose him & tjey made me feel like I was going to/ needed to. definitely being overdramatic but is it that crazy that I found the person I want to be w forever and it just happens to be my first serious relationship? also; how do I resist the urge to compare myself to others relationships, because it's adding so much anxiety into how I view my own relationship
