Hi,
Sorry for the late response, I haven't been around the forum much lately, I'm sorry to hear you're struggling so much
So to address how you are trying to cope with your depression, I'm not going to lecture you on the dangers of self harm and alcohol, I'd be patronizing you if I did. It sometimes helps to treat your depression as if it were a physical being. If a bully was yelling in your ear that they wouldn't stop yelling until you punched yourself in the face, would you do it? Don't allow your depression to hold any more sway over you than you would another person. I find the best strategy for me is to make every effort to not give myself time to think. When I stop and think, that's when the depression grabs a hold, and once it's got you, it'll likely have you for the whole day. Even if it's just turning on the radio, you have to distract yourself somehow, think about ANYTHING but your depression. There will be times where you really can't think of a thing you want to do, this happens to me frequently, but once you force yourself to do something, ANYTHING, you WILL feel better, I can promise you that.
I know what it's like to feel like people don't notice you or care about you. That's a feeling that creeps into my mind often, I've been single for nearly a decade and live alone most of the time. Humans are social animals, we need to feel like a part of a group or we get lonely and depressed. On occasion I've called one of the free mental health advice lines and just chatted to the person who answers about how I'm feeling, it does feel nice to have a listening ear, even if it's a stranger, and the people there are trained to be good listeners.
It's natural to feel like you want to run away, that's a human response too. You are finding your environment hostile or unpleasant, your instinct is to get out of there to anywhere else. The problem is, you can leave, but your problems follow you. You need to find the way that's best for you to keep that being in a little cage where you can keep tabs on it only give it attention on YOUR terms. Ignoring it or bottling it up won't solve anything, but you need to be fighting by your rules, not being assaulted by this bullying little creature.
Wishing you all the best.
James
