So for the past few weeks I have been feeling dizzy and light headed, and after words a headache happens. This happens for about 5 to 10 seconds. And after the dizziness and light headedness goes away, I get a small headache. It just happened about 5 mintues ago and now I feel lousy with this headache.The first one happened two weeks when I was at work. I was stocking shelves (and also a back up cashier and constantly go up to help check when needed and going back to the back of the store to our drinks isle). And I was at register, checking out customers. When I all of a sudden felt dizzy and light headed. I even had to grab a hold of the counter to keep myself up. I closed my eyes and I was fine. But then had a headache. I think I didn't hide it well either as the customer I was trying to check out asked if I was okay. And I said I didn't know.I don't think I was dehydrated. Because at work I do carry a water bottle with me and during break I drink a pop (for that extra engery boost, for those late night shifts). And also during break I'll eat something (usually fruit). Yes it's true I don't drink a whole lot of water (though I'm trying to get into that habit. If I'm luky I drink usually one or two 12oz glasses of water a day (or a 17oz bottle of water while at work). Because our store doesn't have good air conditioning (or heat) in it so that's why I bring a water bottle. But it's been getting a little worse. I've gotten this twice a week now. When before it would only happen about once or twice a month.I'm wondering if maybe this could be stress? Because my parents did divorce two months ago. And I'm loosing my house (that I live in with my parents), and I checked my heart rate on my Note 4 phone and it has been high. My Samsung rep who visits our store once or twice month was shocked to see it that high. But I told him why and he said I could be just stressed out. I'm a 25 year old female.  So could it be stressed? Because I did have to take a week off of work three weeks ago because of stress (or so I thought). Because nothing I was doing was making me happy. Normally if I felt down I would knit, do embroidery, play video games, or listen to my favorite band, or watch my favorite movie and I'd be fine. But that wasn't helping. In fact I was feeling more down. And more irritated when my Mom would come to the house and take stuff from the house that wasn't even hers (and was actually mine that I bought for me). And she would fight with me over who's it was.So any ideas? Should I see my doctor and see if it's stress? or something else?
