My insurance only covers $300/year while my T charges $120/hr. So I pay fully out of pocket. The way I view it, is it is an investment in me similar to paying tuition to get an education.

I wouldn't let money be a barrier to stop therapy. Lots of Ts have sliding scales so I don't think you should feel guilty for not paying his full fee. I'm sure his quality of life won't be affected by you paying him less than the $120 he charges. I would pay whatever you can without having to get a second job or any other extreme measures.
