My heart goes out to you as you face this overwhelming time of deep suffering. Anytime you want to express your feelings, give yourself the freedom to come here and do just that. If you feel the need to vent, go for it. If you feel the need to wonder or question, go for it. Even if you feel the need to come here just to read over what everyone's written, without you feeling the need to respond, go for it.
I wish we were all raised with the idea that feelings are everything, they're so incredibly vital when it comes to feeling your way through life. Feelings allow you to feel or get a sense of when you're around depressing degrading people or in depressing situations. They allow you to get a sense of when people or situations are far too stressful for your own good. They can tell us when we're in the wrong job or the wrong circle of friends. They can even tell us what we can no longer tolerate. May sound a bit silly to some but feelings are our compass in a way, telling us where we are in life as well as giving us a sense of direction (leading us to move away from that which we can no longer tolerate or that which no longer serves us).
When you say you need to talk about your feelings, consider this as addressing 'How do I use/make the most of my compass?'. While many through life will say, in one way or another, 'Put it back in your pocket' (suppress your feelings), my mantra is 'Take it out and master your ability to use it as an incredible resource'.
Looking forward to hearing from you :)
