Dealing with insecurity

ann

Please help me with advice. I'm in a long distance relationship, I met this man 2 weeks ago, I went to visit him and we liked each other, actually I became quite attached to him and I am afraid a little bit too much. He promised me to come and visit me in the end of June. I understand his way of thinking, he wants to take it slow, he liked me but wants to spend more time with me naturally before we decide anything. And I am in no way intending to move faster than him, I want to give him all the space and time he needs, and let him make his own decisions.
I understand all this. But there is a problem, and it is entirely my problem and I don't know how to deal with it. I know that we don't have to communicate every day, especially if he feels that it is too much for him. But before we did, and it he seemed to be hapy to talk every day with the exeption of some days. I assume now that we know each other much better we just don't have so much to tell each other on a daily basis, messengers are so impersonal. But knowing all this I still panick every time he doesn't talk to me, I think that he doesn't need me, is not interested in me, and just disregards me. Somewhere in the back of my mind I understand that may be I am wrong, but the fear takes over.
I think that if I am patient and don't create unnecessary problems this relationship can work out being that he likes me and is interested in me and intends to visit me, and I live quite far away from him, so that should tell me something.
How should I deal with my irrational fears, impatience, insecurity, anxiety? I am disgusted at myself when I feel this way, I am an emotional wreck and I hate myself and I am sure he would not like it too if he knew. So far I didn't show that too him, I am not rushing things, but it is hard. If anybody has similar problems or knows of any ways to deal with my problem, please help me with advice.
