I sometimes find very hard to fall asleep, when i go to bed and lie down heart rate increases and i am stuck in loop . This has started happening recently after I recovered from dengue , earlier no such problem was there . Similar issue was there with me 4 years back , i was not able to fall asleep and this turned into a fear for me. Since i have recoverd from dengue, i am also feeling a bit low, like somedays i feel what to be excited for , life has turned monotonous , i am living alone so feel need of loved ones around also sometimes.
