It would help the folks who would answer this if you would reply with photos, both of the whole plant and close-ups of the leaves. See Attach photos and files.
I understand very hard to get help./ We have had this catus for at least 12 years. Was just a small plant when received . If this helps with our experience phoots attrached
It's a Euphorbia (a succulent, not a cactus). Looks reasonably healthy, but could probably do with better light closer to the window, it looks a bit etiolated ('trying to reach for the sun'). Note: if you ever want to prune it at all, avoid any skin contact with the white sap, as this is toxic and can cause skin burns in some people.
