Peep I agree. I take anti depressants and have increased the dose since my dad died due to not wanting to crash as I have a very bad time when that happens and I have found that they are keeping me on an even keel at the moment, even though I do get upset from time to time, obviously, but not the deep dark depression which I have suffered from in the past.
Nonnie Tricks of the trade are to buy yourself or watch on youtube, things which will lighten your mood, things which you get comfort from (I watch old 70's sitcoms or 80's programmes), watch a comedian, listen to some music which does not remind you of anyone, find some new music for yourself, edit the programmes you watch on tele (I took out the news and now do red button at night to catch up), buy some "indoor clothes" which are slightly more being dressed than bed wear but not going out clothes, like a lounge suit etc., get a dog and take it for walks, or a rescue dog.
Also on youtube there are lots of motivational speakers, along with people who have suffered with depression, a lot of them only young people. Look these up maybe, get some positive thinking going on. Buy a Chicken Soup for the Soul book, or some poems. Go swimming, gentle exercise. Eat well, rest plenty, laugh often. And if you feel like crying then do so but don't feel guilty, just do it and enjoy the release it gives you. But try to laugh as much in a day, or smile at least. Smile at passers by. Hug whoever you can. If you don't have anyone to hug, book a massage, the body contact will be wonderful for you. And I might help the mind and the sleep. If you don't want a dog, buy a budgie, wonderful pets, and will keep you entertained and a reason to get up.
Yes this site is wonderful, I'd have been lost without it these last few years. Everyone is lovely, well, nearly but they know who they are!
