Seek mental help?

So like I’m just wondering at what point do you need to seek mental help? I kinda think I’m not totally mentally healthy. Like today I broke down crying in the middle of the library when I was talking to my bf. I am definitely really stressed rn and I have a lot on my plate. I’m trying to find a job for after graduation. My thesis is four weeks behind. I have an internship at a hospital. I’m planning a service trip for spring break in three weeks. I get my MCAT back in 4 days which is freaking me the fuck out. I’m putting my application together for med school and I have to apply to my college first which is due next week. I also TA two classes and have my normal course work and I’m just trying to enjoy my last semester in college. Like considering everything I have going on do you think that’s normal to just break down crying? Like I’m super stressed and under a ton of pressure.
