The basic and most common word for to think is "att tänka". "Jag tänker på dig" I am thinking about you.
(Also "Vad tänker du göra?" What are you going to do?)
"att tycka" means basically opinion, guessing and the english often use think.
"att tycka om" means opinion too and liking, there too thinking is sometimes used.
-"Jag tycker att det är rätt" I guess/think it is right (opinion)
-"Vad tycker du om saken" is like: how do you like that, how do you imagine... > What do you think about that? (That can be an opinion too?)
-"Jag tycker om Bach/om din skjorta/om dig" (liking, opinion)
I know that explanation maribel, thanks, But I think our problem is cause the sense of the sentence is complicated, because, it would be:
(1)I'm thinking of You, hope you do the same, try to trust in me, your honey/sweetheart
(2)I liking you, ..., try to depend on me...
(3)I'm thinking of you,..., try to depend on me..
(4)I liking you,...,try to trust me...
