Will I Be Happy?

Hello. Lately, my life has changed, like a wheel overturned. A few months ago, I started studying in Sofia, and everything was very good. I was worried, but I managed and got used to it. Positive things happened to me when I met new people, new acquaintances. I started dating a boy we have known for a long time, but before I started being in Sofia we started seeing each other in the city I am from. There were times when we saw each other, but there are also moments when he doesn't remember me. I feel terrible at times. Time passed and I asked him. You don't seem to want anything serious from me? And he answered me: You are seriously confused. If I didn't want anything, would I write to you and that's it. I told him you weren't there, you don't remember me. Besides, things didn't go my way with him ... I've been gaining weight lately. I don't know why, maybe because in the summer I limited myself, I lost weight and when I went to Sofia, I starved all day and in the evening I had a big appetite. But I don't like it that way at all. I was 60 kg, and now I weighed almost 75 kg, I was terrified. Yes, I am 1, 75 tall, but these kg do not feel good. I don't know how I got to that kg. My other problem, which is perhaps the most important because my career depends on it, is education. I study in Mu Sofia, but I don't get used to hospitals with the whole atmosphere and the patients. In short, I have no place to work in a hospital. I like it and I always wanted to become a doctor, but it is the most complicated profession. Life depends on you. And I am faced with the dilemma of continuing in the field of medicine or something else. All this is on my head and I feel depressed and the only thing that improves my mood for a moment is the sweet. But I gain weight from it and nothing good follows. Thanks to everyone for the comments. Nice day
