Help

Help, tomorrow I go to school again but the problem is that I am the least sociable person anyone knows, I don't know how to act with new people and I'm afraid of not making a good first impression.

I'm so afraid that I like someone and that they supposedly like me too but that it's just a farce, they'll get my hopes up again and make me shitter than I am, it scares me because when I fall in love I give everything, I don't know limits and that makes them always take advantage of that and it annoys me so much, I want to start crying but it would be pure shit and I don't think my parents would care because they would most likely tell me something like "well ignore it and that's it"

That's all, I wanted to vent since I really feel in shit, bye :P
