You sound terribly depressed and I hate that for ya. .i know what its like; it could be you need medication to help you with that. Which, there is nothing wrong with medication if it helps you take your life back and live it.

Classic signs of depression are sleeping too much and not caring about even the simplest things.I think you should see a doctor. You could be having a chemical imbalance, or a thyroid problem that is causing this and if so it can be helped fairly quickly...age is not a factor with thyroid problems either.
Or are there other reasons for your dsepression? my therapist says depression is anger turned inward.. is that a possibility for you?

I think a good thing would be if you can force yourself to get up and go for a walk outdoors... even for 10 minutes.. get out into the sunlight..it helps with depression too.Sometimes you have to be hard on yourself and make yourself do things you just don't want to do and then as you continue to do this, it gets easier.

I totally understand about friends.I have friends that have been in my life for more than 20 years and I find myself alone... they are not the kind of friends I need anymore... I have grown and changed beyond them.. it may not be that you are boring.. it may be that you have grown apart.. it happens.

What about church? Do you have one you can go to where you can meet new people? I belong to an Assemblies of God church and they have great youth groups...it could be the way for you to get out of this slump you are in...check into it... make yourself take the step out of the dark place you are in.

I hope you feel better soon hun... truly I do.. your whole life is ahead of you.. you deserved to be happy.Pm me anytime...Faith
