You sure do seem angry. I know what that is like, since for a period in my life I was also angry all the time. Now I can honestly say I find anger, and especially hatred, worse than sadness or numbness. Sadness is personal, while anger and hatred not only cause negativity for you, but also for others. And hatred can blur your vision as nothing else can (that's why they call it "blind hatred").
Hatred is something personal, and thus there is no universal way to get rid of it. One important factor is that you really want the anger and hatred to be gone (which I assume you do, else you wouldn't have posted here).
Personally, I have a little philosophy considering hatred. Let me explain. Try to imagine being raised with only love, never arguments, fights, etc. I do not think you will grow up to be a happy adult, but rather a sort of jelly that will collapse with the smallest resistance from outside. To grow patience, tolerance etc., you will need enemy's, people that stand up to you. You in fact need people to wish the worst for you in order to grow ever larger tolerance. Because you will not know and can not practise tolerance unless you have an enemy that puts you in a situation where you can practise is. Still with me?
So, if you extend this philosophy, you can say that enemy's are negative things that wish the worst for you. But every negative things has a positive side. For instance, the shrinks. They may be liars, but at the same time could be loving fathers/mothers. Finding your "true" enemy can be hard, since real enemy's are rare. There is, however, one thing that only wishes your destruction and the destruction of everything around you. It is called hatred. Hatred is the ultimate enemy, and thus the ultimate source for practising tolerance and patience. Overcoming hatred can lead to no more anger.
A way to overcome the hatred is to be grateful towards it, since it will give you the chance to practise patience and tolerance. Being grateful, or positive, towards something will transform it into something positive as well.
I know the above can sound rather weird, but things like that are what keeps me going. Maybe you can find use in it, maybe not.
One more thing though. If you never trust anyone, you will never find trust. It sounds obvious, but you simply can't achieve something without trying. If you feel like you want to have someone to trust, there is no way of achieving that wish unless you try. It is just a matter of attitude to say "no one is trustful and perfect" or "every one is trustful and perfect in their own way".
Tasha, I hope this helps, even the smallest of help would be worth the effort. Please ask yourself the question whether you want to get rid of the anger, hatred, depression etc. Because if you want, there are uncountable roads towards achieving that.
All the best!
