I went back over your other posts, it did sounds like you put your aquarium together in a hurry. This now means you have to cycle your tank with fish in it, which can be very hard and yes, it can stress your fish. So, you've started your tank in late March? It can take up to 10 weeks to develop a well cycled tank sometimes.
So what to do about your little guppy? You might want to do water changes more regularly to decrease ammonia. There's probably more you can try, but you'll have to wait for the advice of others.
