From what I can tell, you are feeling overwhelmed by your thoughts and have been feeling low. Your mind is filled with several questions that you can't find the answer to.
This suggests that there's something in your unconscious that's trying to come out. Your thoughts are having an impact on your emotions, which is why you're feeling low. Here are some things you can do:
1. Concentrate on your breathing and take deep breaths. Instead of focusing on your thoughts, focus on your breaths and count them.
2. Channelize your emotions physically and partake in exercise. Move your body--you can look up a workout video on YouTube or go for a walk.
3. Write down what you're feeling and journal your emotions and thoughts. This will help you recognise your faulty thoughts and challenge them as they arise.
4. Talk to a friend or a close family member who can provide you with safe space and empathy.
5. Meditate.
These techniques can help you overcome your thoughts at the moment. However, if you're still feeling overwhelmed and are overthinking, it is time to consult a psychologist.
Next Steps
