I know the thoughts you are having all to well. Yet, how bad they might seem, you can turn them into something positive. Use the thoughts and the feelings you have to make you aware of the state you are in. I used to think (and still do sometimes), that no one will ever love me. While thinking that, it wasn't the others that didn't love me, it was me not loving me. Whenever in that mood, I became solitary, sad etc. I never sought others to share my grief with, or just to be with. However, when I did felt good about myself, there were a lot of people that liked me, and some that even loved me.
There is your outside and your inside. While you can take care of your outside, you can in fact totally change your inside. And the people that will give you most joy will be the ones that will look how you are within, rather than outside. The outside will change, will fade away, and people relying on that to love you can stop caring for you because of something inevitable. At least, that is my opinion on it. And it works so far.
I suggest you try to love yourself. Yes, it just might be the hardest thing to do for the depressed, yet practice makes perfect. The first step in loving yourself is accepting yourself, which is kind of a big step too. I just take it bit by bit myself. For my body, I say for instance "Do I accept my left big toe?", and so on. When I encounter something I don't accept, I will split it into smaller parts until I accept all the small parts, and thus the bigger part as well. Or if I just can't seem to accept it, I will ask myself the question whether it can be changed into something I do accept. If yes, I will do my best to change it, if no, there is no reason to feel bad about it because there is nothing you can do about it. I haven't found anything I don't accept up to this date.
Some goes for the inside, though that was easier to me. I am who I am, and for no money I would change into someone else. Just being aware of this makes me feel good about myself, maybe that it will help for you too.
Take care Eli, and remember to keep talking to us whenever there is something on your mind!
Acceptance is the key
The World is but a reflection. Smile, and it will smile back.
Try to keep smiling! :)
