Ever heard the saying when it rains, it pours? Sometimes life just hits, and hits hard. I'm not saying there's no possibility that there is something deeper going on, but many people go through incredibly rough periods like this several times in life. When one bad thing happens, often that can lead to a spiral of events, no outside force necessary. It's often easier to look for some outside force to blame, when there might not be one...
That said, there are some traditional ways to tell if you've got the evil eye on you. One way is to take a small bowl of water, and a bowl with a little olive oil in it (or another vegetable oil would likely work). Bless both however you're comfortable with. Put your finger into the oil, and then quickly move it over the water, maybe about two inches above the water. Let three drops fall into the water, one onto the other. One large oil drop in the water is a good sign. If the oil scatters from itself (the second drop pushes the first, the third the second, to three different ends of the bowl), or mixes with the water and becomes very murky, that's a sign the evil eye is present. You'll want to do some sort of uncrossing working at that point. (I usually recommend a bath or shower, if you can get the herbs for it - traditionally hyssop and rue, but there are other options. Frankly, even if it's not the evil eye or a curse, it's a good way to purify and remove any crossed conditions from you, which might open the way to solving some of your issues.)
Another method is to rub an egg counter clockwise all around your body (touching it), from head down to toe, right before bed. Sleep with the egg under your bed. In the morning, break it open. If it looks like a normal egg? Nothing was wrong. Egg looks very rotten? Very discolored? Very murky? Evil eye was present, but has been removed. The egg neutralized it, so it's not "cursed" in itself, you can just toss it into the trash.
An actual curse is a bit more tricky. Since you don't know anyone who could do that, I'd say it's probably not that. But, if more time goes by and you really believe you are cursed, I usually recommend you get someone to do divination for you to see if you are cursed if you really think that to be the case. (But not from someone who sells curse removal services, because often they want to sell that product...) If you can be very removed from your situation you might divine for yourself, but it's often better to get another opinion there.
I sing of you, blessed, night-winged Dream, Messenger of things to come, greatest prophet to mortals, in the quiet of sweet sleep you come silently and speak to the soul.
