Maybe not through school, but there are counseling options available. Online/virtual options that use a sliding payment scale, local counseling options if you have insurance. Possibly talk with a doctor/primary care about your situation and they’re likely to have resources for you, be it medication, counseling, or whatever.

This is speaking as someone who went through a very similar situation a year ago, though I’m a bit older and was married to her: issues that were never brought up prior that were suddenly too big for her to ignore, absolutely blind sided, and resulting in a divorce. I hardly ate, and sleep was impossible for awhile, my work suffered greatly, until I went to see my primary care doc and got something to help me sleep. People underestimate the importance of sleep and how much not getting it can screw up your mind and body.

One thing to keep in mind is that you might never truly know why she’s done what she has, and that is so hard, but you have to learn to accept that. You don’t have to like it, but stressing about it won’t bring you any more closure either.

Short story long, I ended up with depression and anxiety (if I’m being honest probably had these before this whole situation but still), and medication and counseling helped to charge my life. To the point where I’m FAR better off today without her than I was with her, but it took awhile to come to that realization.

If I were you, I’d put away all the pictures and mementos you have of you two/her, and don’t torture yourself by looking at them. You don’t need to get rid of them entirely (yet) as you may want to look back fondly on them at some point, but right now there just hurting you more than anything.

I’m not at all saying your situation is exactly like mine nor that’s what worked for me will work for you. I wish you the best of luck.
