Cómo se dice en inglés "chupar la sangre" o "sangrar" de manera natural? "Suck blood" es la traducción literal, pero no sé si sea correcta o si suene natural. Agradecería uno que otro ejemplo, por favor :)

I´m happy by talking to my bad friends About a month ago, I saw a picture that a friend shared on Faceook, I commented it with the usual lovely words I always talk to him. Later, I realised my comment was not anymore, I felt terrible. The same day he sent me "hey" in private, I asked about the post and he said "sorry, I deleted because (female name) can get mad". I felt really sad, and didn´t ask who was her, I imagined. I felt very sad and thought "So you care more about what thinks the girl you are having sex with these days than our friendship of years? I HATE YOU" I stop talking to him, he said "sorry" and that stuff. I ignored his messages. Two weeks later he sent me message again, I remember that he was really trying to get back our relationship so I replied. After that I feel happy. I don´t use to forgive anyone but what can I do if I see he´s really sorry; even if he is really proud, just like me, and I love him as a friend (the only way I can love haha)!. I think "Maybe it´s a mistake", but I´m almost sure he thought the same. I hate having this big, kind and weak chicken heart (chicken because it´s too weak). HAHAHAHA Well, this is what my friend told me it happened to her.

¿Cómo decir "no sé por cuánto tiempo"? por favor Yesterday I was thinking about something but I couldn´t translate to english this part. Example: I got this and it´s useful but no sé por cuánto tiempo. It´s correct if I say "for how long"?

I don´t know what´s the correct use of "should" in a question. Could you help me? When I say "I should go?" is it correct? or it should be "should I go?" or "shal I go?". I think my problem it´s about syntax, isn´t it? I want to write natural but also proper.

I would like to know when should I use "no to" and "don´t", please

How to get happiness? 1 Recommendations 1. Have satisfied your phisical needs; food, drink, house and clothing, and a way to keep getting these stuff, like a job. The last is essential, since it´s difficult to think that one who is not nourished and has no home can be happy. Unless we are the kind of people who don´t feel need of have a hause, because their adventures in montains, in the forests or living on the streets, somehow make them happy. This because living in those conditions let them create good memories bassed on theirs experiences, as good as bad. But, if you do have the need of a ceiling (how do you say in english?), get it. 2. Make an analysis about what you have lived until now, doing a deep refletion can let you understand what have made you get great happiness until now. Judge each moment you have thought it was important and why it was. For example: "when I was in highschool and a boy defended me against many classmates, I feel cute, and since that day we have been good friends", "when I visited an electronic store and I won a computer in the raffle they did, before, I never won anything", "when we go to Machupichu, I loved the landscape, I couldn´t imagine what was (was because I´m talking about ancient Peruvians) to live daily in heights, having always that beautiful landscape". It´s advisable to check each one of these memories that, in their moment and even know while remember them, make us feel good. Wonder few questions about these remembrances will be very useful for us.
