In the dumps rn

Honestly just need to know it’s not just me. It’s will all seem stupid That I’m even struggling I’m sure. I’m a 21 year old women working as an ultrasound tech. Already finished my bachelors been in the field working for two years. Everyone is always saying you’ve gotten so far in life already and honey you have so much ways to go. Anyone else love their job but hate how they get treated because they are so young? I know it’s easy to say “it’s because they’re jealous “ or whatever but honestly just makes me feel like I don’t belong. Like I shouldn’t be working. It might be my mental health just not being it’s best right now but I just can’t handle anyone right now.
