If that makes you feel bad, depressed, and scare I would suggest to actively stop reading online news or taking part in online, public discussions. Your feelings have no influence with the situation, if it is creating pain there is no shame in disconnecting for some time. Look for people or groups you can meet IRL for simple activities. In the past I found that playing board games with strangers was a really good way to have a break from the depressing events, and you can often find open boardgame groups around you by looking on meetup or similar platform. If you feel depressed for a prolonged period of time (more than a few weeks) I would recommend you to contact a psychiatrist in your area, just by precaution. They can help you put words on your negative feelings, diagnose potential troubles you may be facing, and recommend adapted measures to support you (not necessarily medication, that's just an option). I myself went through this process during the past year or so, that has been really helpful so far to deal with my depressive thoughts, identify some patterns in my thoughts and behaviour, and mitigate the negative impact.
