Feeling after leaving here for 5 months

Sorry, for not updating it too often, don't have time and too much internet access at my home during the evening.

Just want to share how do I feel living here.

I feel that I don't have any real friend. Sometimes you meet person, you have great talk, great time and you feel that this person is becoming your friend. And then happened one of such things:
1) They don't have time for meeting you.
2) They just don't pick up the phone, when you want to talk or to agree in some meeting.
3) If you agreed on some meeting, they just cancel it in the last moment, when you even cannot find anyone more to spend the evening.

Today I feel that here is no person (except some european friends, who is in another city), whom you can trust. If some person from latino america tells you "YES", I want to accept it like "YES", but I need to accept it like "There is some posibility" (here easily can be told NO, to some your plan in the last minute, when you need to go/do and they don't feel bad about it). And I feel that I cannot live with it, I'm feeling so lonely with "friends", who in order to say that cannot or don't want, just don't pick up the phone. Do they feel that if they say me true situation, I will scream on them or I will be angry? I will be good with it, I will see the reason and will understand, but when you, in place to hear what is happening, hear just "beep" in you phone and think does it mean that person don't hear your call or just don't want pick up, I cannot stand it, I feel really disappointed in people, I feel that all this friendship what they show is just "artificial" and in reality they don't care about you.
I have no idea, what should I do, in order to find at least 1-2 good friends. I really hope I can change my this opinion, but I don't really believe that it is possible.

I want my latvian friends here, whom I can trust, whom I can meet when I feel alone, ...
I'm thinking what is better to hear from people "I don't have time" or to hear "Yes" and then don't meet person.

Seems I need to wait it for long time or to do something to change this bad situation with "friends".

I had one case with mexican friend, who told me how it is in reality. "If someone don't pick up the phone, it means you can cancel that plan and make another". But it is not right way to do things, in my opinion. What to do?

And also about do something. So many times happened here, that you ask someone to do something, he/she told you "Yes" and then you ask it later, when things should be done and you hear, I will do it now, when you already lost the time. I had sooo many such cases. Do people has responsibility feeling for their words? Seems words for them is just words, not promise or commitement.

It is easy to say just adapt, but I don't want to become the same, I don't want to be the person "What I feel, that I will do", I want to be person, who use time in productive way, live is going and opportunities is passing. I don't want to lie on the bed and see, how they are going, I want to take them. May be it is my first on last time in Mexico ...
AND I WANT TO TRUST PEOPLE...
