Hi! Thank you SO much for all the advice! I will write a bit more later, now I'm replying to the wasp issue.

Thank God I have never seen a wasp nest in person, still they are EVERYWHERE in the city. So, I'm trying not bringing any sugary stuff or fruits with me to uni, and I'm using a minty-herby scented shampoo instead of those tropical-fruity ones. Same with soap. And I never wear yellow. In high school every grade had their own color, it meant you had to wore that T-shirt during PE classes. Guess which color my class had - yes, YELLOW. Ohhh nooo. The first few lessons outside were a true NIGHTMARE. Really. I quickly switched to plain white T-shirt, which made things a bit better, and I didn't care about the teacher saying 'What, are you in another class now?' No, but I don't want those striped beasts approach me. (Later almost every girl changed to white because they didn't like that all the bugs liked their yellow T-shirt. And we never had a problem about it. The teacher didn't say anything bad afterwards either.)

I have never been bitten by them, or by bees or anything except mosquitoes. I think it's because I don't really jump, just escape as quickly as possible. This is of course harder in closed classrooms (once I had to spend a day in an office as part of my studies, and guess who visited me - yes, a wasp. I couldn't focus on anything else until that thing flew out the window...), tram stops are quite limited as well...and trams are the worst. Yellow AND limited movement available, especially on a crowded tram. Once I invited a friend home and I was talking about how much I hate wasps. We got on the tram...and there were at least THREE of them. On the tram. I got crazy. I kept hurrying back and forth. Whyyy...Can't they fly? Why do they need those freaking trams? They don't have valid tickets, they need to get off! XD

Can this be even cured somehow...?

Thanks again for your suggestions, I will come back to them definitely.
