Hi Wants2fly. I personally don't see anything wrong with wanting a lot of support from online friends. Often it is best to get support from people who don't know you personally, because they can be less judgemental and more impartial. When I was very depressed, I spent as much time as I could getting support online, and for a long time after that I spent most of my day online. It's only recently that I've begun to live a life away from the computer.
So if you need support, and you find that support from your online life - then yes, stay connected. The only danger that I can see is that you get too involved with your online friends and neglect your friends and family in real life, and therefore isolate potential helpers. I too know what it is like to know there are certain times when you feel lonely in real life - for you, you find it is the weekend. So then, how about seeing it as some personal time to spend on yourself? Rent videos, spend time exercising, visit local attractions, spend time with family, etc. Only a suggestion, since I don't know your personal circumstances...
