Envision, your timing for starting to criticise someone who's suffering is really terrible. There's no need.

lostandlonely, one thing I find that helps when you're feeling down is to just keep active. Allow yourself to feel sad, but try and act otherwise even if you don't feel like it. Arrange to meet up with old friends, join some local clubs/societies and try and keep socially active. Not only does it distract you from brooding about the bad stuff all the time but it can also lead you to feel better about yourself just through having some meaningful interactions with other people.

Really sorry to hear how upset you're feeling but it will get better if you just hang in there.
