any advice !!

I'm six weeks and three days and I'm having trouble eating. I'll say I want something then when I smell it smh I don't want it. Some days I don't eat at all because I don't have an appetite. Not to mention all the stress I'm under , me and my boyfriend broke up last night. I can barely sleep, I'm always feeling hot and cold, takes awhile to get comfortable. Does anybody have any advice. It would be so helpful. Thank you in advance ladies.
