I know this is long, but please read the whole post. I have invested much time into edifying brothers and sisters in Christ who experience these deeply troubling problems, and I want to edify you s much as God has enabled me to do.
The real problem, fundamentally, is that what you are asking of God is impossible for Him to give you. At first glance that may seem an odd statement, until you appreciate that you are dealing with a context of persons and a relationship, not something like an impersonal force or law of nature.
As aforementioned, your emotions and mental states are
personal responses of your heart and mind to what you perceive. To clarify what I mean in my distinction of persons and impersonal forces, there are ways that we understand things to exist that cause us to perceive them differently. When we perceive things which are not persons, we recognize them as having no motivations, no ambitions, no thoughts, no emotions, no consciousness nor will of any kind. Therefore, we readily conclude, that whatever is a mere thing exists the way it
clearly presents itself to our senses.
As an example, think of a simple object like a bottle of water, or a natural law, like the law of gravity. Imagine the bottle of water appears to your eyes to be half full, and when you pick it up, it has the weight of the water. When you become thirsty, it would never occur to you that upon twisting off the cap, the bottle which appeared and felt half full will be revealed to actually be completely empty upon tilting it towards your mouth. Why? It's very simple. As an impersonal entity, the water bottle
must be at least approximately what you experienced it as and can not have had any motivations to deceive you concerning its content, like not wanting to be devalued and consequently recycled. Likewise, you will never suspect that if you were to jump incessantly for hours that you may eventually be trapped in suspense or thrown more forcefully to the ground on account of gravity growing irritable with you testing its patience or having a particular agitation with you. You expect these things to remain as they are and be as they appear because you know they do not have any thoughts or feelings about how you treat or use them.
Similarly, when we think about God (and as you've disclosed personally), we have the same clear content of His Word presently before us as we read, and we have the historical event of the cross on which Christ was crucified for our redemption. However, the fundamental difference here is that now we are dealing with presentations by a
person, who
does have motivations, thoughts, feelings, ambitions and every form of will. So while we understand that God attests to His love for us in Word and deed we sometimes suspect that, like other persons, God can cease to mean what He previously sincerely did (if He ever meant it at all). We suppose that God can grow irritable, impatient and indifferent enough to us to change His original ambitions and desires for us. The problem with this kind of thinking is that it anthropomorphizes God, which means to conflate His nature with that of a human's. To see how that is logically absurd, see my extensive post on the topic by
clicking here. Beyond the logical problem, there is still the ultimate need to trust the person of God as He has disclosed Himself. This brings us to your suggested resolution of the problem, in paraphrase, "why not just give me some experience of Himself and His love?"
This ostensible resolution only circles us back to the fundamental issue, however, which is that God can not give you an experience of His love in the emotional sense, nor would any mere sensation He give you be beyond doubt itself. Let me give you a final example to demonstrate this with the analogy of a human relationship. In a spousal relationship, a husband may attest to many things concerning his intentions, desires and his love for his wife. He could, for example, claim that when he marries he he will be with her for better or worse and that he will truly be forsaking all others til death does them part. However, due to past experiences or intrinsic insecurities, the wife never truly achieves comfort, and, even after many years, continues to suspect that if the right circumstances present themselves (prolonged period of arguments, "more attractive" woman, etc.) he could likely become unfaithful. Even when the husband reaches out and touches and embraces her, and she feels the sensations of his touch on her skin, she could ask herself, "is it really love or is it just how he feels right now?" Despite the sincerity of the words, deeds and affections of the husband in his own heart and mind, the woman herself will not feel the truth of these things simply because they are true. She will only have comfort and security in his love when she believes it is really as he says it is. He response is internal and personal, and therefore can not be a provision but must be a response.
In conclusion, to not drag this on much longer, I want you to understand that, as a person, a true
self, God could not make you feel any sort of confidence in His Word or His deeds as a provision without circumventing the
personal part of you, the heart and mind of you that responds by your own will. Thus, to make you feel God loves you, God would have to actually make you cease to be you so long as you believed it by His irresistible force upon on your heart and mind. For you to truly feel God's love, you must take the clear content of His Word and deed and every reason He has given you to have full rational confidence (again, click the link above for my more extensive version of this argument) and
respond to it in agreement with your heart and mind. Then, at that moment, when you appreciate and accept it's truth, you will feel loved, you will have confidence, and you will have peace and full assurance.
