My two cents of advise would stop reading too much into the experiences you had while meditation. Also have a daily practice of meditation and banishing. Practice maditation such that your mind goes into silent mode. These are important since you were having depression in the past.
Then start working on your astral senses so that you can have a clear communication with the spirit in question. Once you open them, you will have a clear answer on what the spirit seeks from you.
If you are scared don’t do it. Wait till your anxiety eases out.
Making pacts is an advanced form of magic. I have gone through your previous posts and I feel that you are still a beginner. So stick with your daily practices and work on your astral senses.
I dunno what you have asked from Gremori, but she would be happy to see you persistently working on yourself and she will be there when you reach to the point where you can communicate to her directly. Creating an altar is entirely upto you.
Meanwhile, cultivate your energy and use petition spells and evocations for your timely needs.
Lastly, follow your own advise:
Don’t be in a rush and practice magick peacefully. When the time is right everything will fall in place.
