[edit] AskMe Threads and advice about Depression

LobsterMitten offers this broad summary of AskMe advice

seek therapy or other one-on-one counseling for help in breaking bad thought patterns that keep you depressed; make and keep therapy appointments; if you don't click with the first therapist, don't give up on the idea of therapy but find a new therapist to try
maybe seek meds; different ones work for different people
exercise; this doesn't have to be as hard as you might think
be around people (a job with people; housemates; a visit to the coffeeshop once a day); online doesn't count for this
shower, dress and get out of the house every day for at least a little while.
eat enough but not way too much; eat reasonable food rather than all junk food or all contrived restrictive-diet food
sleep a reasonable amount; if you are sleeping more than 10 hrs a day, make routines with help from others that will help you break out of that pattern
don't make up excuses for why you can't do any of 1-7; making up excuses to stay depressed is a big part of depression

When you are very depressed, it can help to just take things step by step. Here is a step by step guide to taking a shower and to doing just the essentials every day.
