Goodness me, you're really in a muddle! It's going round and round in your head and you just don't know which way to turn. But it is really as serious as you think? Not necessarily, but certainly bad enough for you to need time out.
Advice: Take some time out for yourself and learn to let go of your worries from time to time. We see things more clearly with distance, so taking a step back may help you to find a solution. Remember that the sunshine comes after the rain, which is very much the case for you and will help you to stay positive and think clearly.
Finally, if you have unfinished business, or are hoping for a pay rise of a windfall, be patient.
Things don't always go the way we want them to, sometimes there are delays and even the best-laid plans can hit obstacles. With patience and a philosophical outlook you will get through this. Things will get better for you soon.
