hm, i can see the problem, but its really too much, there are some rules in webdesign which dont fit here 🙂 like: the menu should have only 5 or 7 entries, and all of them should be in the same way like nouns or verbs, have the same length and the same amount of words, so they are all “equal” in a way, all of them are same and same important? so maybe you can shorten the text of the menu entries for the longer pages, like “impulse” instead of “impulse zur veränderung” or “person” instead of “sibylle tobler”? (im german native) you could also use a house-icon instead of “home” and you could make the size of the font in the menu smaller or use a more narrow font?
