<s>[INST] I;m going through spells of depression a few times a week and then it seems as though Im full of energy. Im sleeping a lot some days; then other days it seems as if I cant sleep at all and on those days Im full of energy and the lack of sleep does not affect my work performance. I cant concentrate, my thoughts race though my mind. My wanting of sex has increased. I have lost interest of the things I have once enjoyed, most of the time I just want to be left alone with my thoughts. Im afraid of talking to someone about this. [/INST] His understand your concern. Frequent episodes of depression need evaluation for different mood features. Mood reactivity need to evaluate properly. Frequent episode sometime may indicate bipolar disorder. So consult psychiatrist. After proper evaluation we are able to do proper treatment. It can be treated with SSRI and mood stabilizer. So consult and get help. Still if you have a query then feel free to ask. Thank you. Take care. </s>
