You’ve mentioned that these symptoms have been affecting you for around two weeks, which is a short time frame. This means that the problem is still in its initial stage. Therefore, it may not require long term medication or treatment. Usually, with symptoms like these, it’s either anxiety or depressive disorder. But, for now, that’s just a guess. Like I said before, these symptoms aren’t enough to give you an exact diagnosis. However, we can evaluate them in order to identify the intensity of this issue.
Anxiety has a wide spectrum of other symptoms such as restlessness, difficulty to concentrate, forgetfulness, irritability, fearfulness, as well as physiological problems like palpitations, shortness of breath and fasciculation. Feeling guilty is mostly associated with depressive disorder but since most of your symptoms aren’t related to that, I’d say you might be suffering from an anxiety disorder. The best decision here, for you, would be to visit a psychiatrist as early as possible. The earlier you get diagnosed, the easier it gets to manage your mental health status and chances of recovering without medication are also higher. You’ve mentioned that it’s mostly during the night time that you feel uneasy, overthink your regrets/guilt, and end up crying. The reason you are crying at night in particular might be because you are always occupied during the day time and you don’t have time to think about anything else. And when you’re free, you end up feeling every emotion at once, which pushes you to cry. That might also be the same reason why you overthink. Since you particularly mentioned that this started happening two weeks ago, I would suggest that you try to remember if something happened around that time that triggered your emotions. There might be something around you, or you might be thinking about something that makes you break down every night. Identifying that will help you understand what to do next. Although it’s best to visit a professional at times like these, I know some people prefer to take some time before making that decision. In that case, try to figure out what has been affecting you emotionally, and maintain a healthy lifestyle. You can exercise regularly, meditate, and have an appropriate sleep cycle. Avoid alcohol, cigarettes or any other drugs for that matter. Lastly, I would like to assure you that whatever you’re going through can definitely be fixed.
