I refuse to see a psychiatrist. I have problems being seen a lot by people in real life, much less talking with them. I will try getting back into old hobbies etc this coming week and see if that helps. An internet timer etc probably won't help, since I know I'll just find a way to remember any password I set, and I don't want to set one randomly for fear that I couldn't get my settings back.
I'll try to only use the computer for 3 hours a day for the next week. Since it's a laptop, it has a little switch to enable/disable internet, so even if I need to use the computer for school work, I can switch that off so that messengers can't log in right as I start.
The only problem I'm worried about is insomnia... I haven't slept with the computer off in 3 months, normally falling asleep while using it (think me as pathetic as you want).
I'll try my best. Thank you for your advice.
