Good morning, it is sunny today. I am going to the university for the first time in a while. I will take the online lectures at my university. I am happy to meet my friends. Going out during the morning is very good, I feel better about myself.

Good morning! It is sunny today (you should separate this in to 2 sentences). I am going to the university for the first time in a while and I am happy to meet my friends. I will also take online lectures at my university (I'm assuming that you mean you go to actual classes and also online classes). I feel good about myself when I go out in the morning (you used passive voice; probably a better way to word it is something like this).
