Should I see a therapist?

You all, I need some advice on weather or not to go to psychotherapy at my school. At my college, they offer mental health counseling 6 times a semester for free. I've been thinking about going for weeks but I feel like maybe I don't have something serious enough to talk to a phycologist about and am kind of embarrassed to ask for help with anger/low key anxiety and other things like low self esteem or self pity when I feel like they're all so temporary. I may be struggling with one of those things I mentioned for a few hours but the next day I'm back and fine again. I just don't want to waist their time and have nothing to say. I'm embarrassed because I feel like I haven't really struggled enough in my life like dealt with abuse, death or financial hardship to be complaining about my life and that I'm being a princess. I know I think a little too much, so my emotions and opinions change quickly. Also, I know sometimes when I get nervous I start crying and I'm a little embarrassed that might start happening if I try talking to her/him 😬😭

Can anyone let me know what I should expect? How it works? Does the psychologist ask me questions or give me a survey or will she just talk to me and figure out on her own what I need to work on? What is tmi? Do they give me advice or just listen? I'm not sure what I'm supposed to do.. thank you 💖
