Burnt out and need help

Hey everyone, I turned 21 a couple of months ago and maybe it’s just adulting but i’m very burnt out mentally and emotionally. I’m working two jobs as a full time student in my sophomore year of college and studying kinesiology to become a physical therapist. Im also volunteering as an athletic trainer at a school to gain experience as well. Im just tired and want to be happy or feel something better because im doing what I love but just either need some time to myself or help. When I do go and try to have time for myself it gets interrupted and I end up having to take care of something or it just ruins the vibe. So i just wanted some insight. I’m working on expressing emotion and also just reaching out to people. I wanted to gain insight or advice from others on how i feel or how to if it is normal and if not to get the help I need.
