Sometimes i feel like i cant collect my thoughts. They come and go all the time. Its getting aggravating and also starting to worry me. Im usually very energetic and clear headed
Hello You have been feeling tired and Chat Doctor.  You have also lost your appetite and also having headache. You are not able to concentrate on thoughts, and you are remaining worried due to these symptoms. There may be different causes of these symptoms, but frequently they may occur due to some nutritional deficiencies like Vitamin B12 deficiency. Low vitamin levels may be a reason behind tiredness and weakness. I would advise you to get your It B12 level checked. Other possibility that may occur is hypothyroid states. Low thyroid level may be a reason behind such symptoms. Thyroid function tests are advised in such cases. Other possibility that may be aggravated by low It B12 and thyroid levels is Depression. In milder forms of depression such symptoms may be seen. I would advise you to please visit a Psychiatrist for detailed evaluation of symptoms. Thanks
