<s>[INST] Hi im a 31 year old male, and for the last few years I have gradually started to feel tireder and tireder I every now and then have a heart issue were my heart seems to go really fast for a few seconds and then back to normal this is normally when laying on my back in bed. Its the tiredness that has got me down the most as I always seem irritable and dont get on with people as I used too I sometimes have a terrible memory short term is the worst if you could help me with any of these that would b great. I used to be so healthy now im falling apart. many thanks, Richard [/INST] Hi Richard You have many symptoms like 1. Low energy(I have gradually started to feel tireder and tireder), 2. Decreased interest in enjoyable activities (don't get on with people as I used too) 3. Short memory which at your age might be due to decreased concentration and attention All these symptoms suggest you might be suffering from depression treatment of depression-SSRI (Escitalopram, sertraline ...etc.) psychotherapy please consult psychiatrist/psychologist Hope this clarifies Regards Chat Doctor.  </s>
