You have a homebrew character concept where the DM may have different interactions in mind
You've got some houserule/homebrew in here with your character concept. The below represents a rules-based answer to support how it should work, but your DM may think otherwise based on how they constructed your character concept. If they say something else happens, then that's generally what happens.
You should be able to use your familiar to 'see' new forms
The requirements of Wild Shape simply state (emphasis mine):
Starting at 2nd level, you can use your action to magically assume the shape of a beast that you have seen before.
The requirement is that you have seen it. But, as you've stated, you're blind. So that presents an issue. An issue for which you have a resolution via find familiar(PHB, 240).
Additionally, as an action, you can see through your familiar's eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses that the familiar has. During this time, you are deaf and blind with regard to your own senses.
With a Familiar created by this method, you can use your action to utilize the familiar's senses and now you are seeing so that you can find a new wild shape option.
You shouldn't be blind in your wild shape
As you've quoted, you don't retain special senses and you gain the senses of your wildshape. You can utilize any senses they have, but you don't have your special senses or your own lack of sight.
As Dragoonkite's answer suggests, your description of your sense doesn't really match blindsense, but is closer to tremorsense:
...can detect and pinpoint the origin of vibrations within a specific radius, provided that the monster and the source of the vibrations are in contact with the same ground or substance.
Tremorsense can't be used to detect flying or incorporeal creatures. Many burrowing creatures, such as ankhegs, have this special sense.
