don't think completely distancing youself from the internet is a good idea - maybe try to distance yourself from social media if you're using it? social media is kind of a bad thing most of the time and has a negative impact on your state of mind, so to say.
yatsufusa recommends a professional psychologist and i can not disagree with them tbh.

I have two small bits of advice for this situation.
1) Make sure the psychologist you are about to see is an actual 'medical professional', by which I mean a person with an actual medical degree from an accredited medical school. Depending on where you live, anyone who has absolved as much as an 'online course' might be allowed to set up shop and call themselves a "psychologist".
2) Be mindful if you ask random people on the internet for advice in questions of mental health. For all you know any given response might come from somebody more in need of professional help than yourself.
