I think she isn't lying when she is saying you are fine, and not too much. As a person, you are not. You are sweet and awesome. But that doesn't mean she has the time to spare. She has a right to her life, to enjoy it when she is not with clients. That's a good thing, in my book. I am forever grateful that my T is taking care of himself, so I don't have to worry about him. But she should never have given you all that time during covid. That messes with the concept of continuity of care. I know she is still there for you, but to you, who you have no power in this relationship, it is like a breaking of the path you were both on. The continuity is broken, and you now need to focus on reastablishing trust.

I think perhaps it would be best for you and your T to discuss this. To focus on your relationship for a few sessions. To establish new ground rules, so that you gain back your secure footing, that you know what to expect. I heard what you said about having many shifts in your life. I understand wanting to discuss it with your T. But it seems to me that the relationship with L is your anchor, your safe place, and it is less safe now, less stable, less predictable. Your T needs to fix that. Not by telling you that you are not too much (you are not). But by telling you what you can and cannot expect of her post covid. To reestablish a predictable environment and to reestablish trust.
