Just need an opinion

I’m not sure if I should go to the doctors and talk about how I’m feeling. I worry and stress a lot about nearly everything I do and I get a sicky feeling and headaches when I’m like that. I also lay at night with a guilty like feeling in my chest but I can never think of why I could be feeling guilty and it keeps me up at night. There’s time when I’m nervous to wear something because of how I look in it and other little things like that. My general mood isn’t exactly great either but when I’m with my boyfriend or out with my friends none of this is on my mind so I’m not too sure on what to do.
