Hello Waqas, thank you for sharing this openly.
Wet dreams are a normal, healthy part of male physiology. They don't cause weakness or harm on their own.
Weakness where getting up from sitting feels difficult can have many common causes, such as low vitamin D or B12, anemia, thyroid imbalance or low potassium. A few basic blood tests from your physician will help rule these out. If the weakness is getting worse, please get checked the same day.
The constant worrying thoughts you describe are very common and respond well to the right support. In homeopathy, every person is treated as an individual, so your sleep, stress, diet, emotions and full history all matter in choosing what suits you.
A detailed one-to-one consultation would help understand your complete case and guide you step by step, in a private and comfortable setting. You don't have to carry this alone.
This answer is for general guidance and is not a substitute for an in-person consultation.
