Is it possible to have forgotten how to feel?

Years ago I went into a shell and subdued all feelings because I was so hurt by something. I cannot open up to anyone now because I am so used to not being vulnerable. When my friend was asking me yesterday what my passion was, I didn't know. Then she asked what made me happy and I really couldn't tell her because I don't even recognize my own feelings or thoughts. I have just gone through the motions the last couple years.

I am into philosophy and it makes me calm reading it, but I cannot interpret my emotions or feelings and have been this way for a while now. This could just be depression but the thought that my life is just school school school of something I couldn't care less about, then work work work at something I hate, then I die is all that consumes my thoughts. It brings up the obvious "what's the point" when there obviously is one.

So right now I need something to live for, because without a rhyme or reason I don't know how much longer I can continue this charade. How do I feel happiness or love? That's all that I can figure is the reason to go on. But without being able to feel happiness or open up, I feel hopeless. Opinions?
