However, you might be projecting some trust issues. No matter if or not, just enjoy yourself and try to keep up the mental hygiene of a safe environment as good as your lives allows you to.
Everybody has problems in his life that normally don't show up on the surface. I am not telling you to just "smile your way through", but do you feel that it hinders your daily life and affects you that much?
The way it sounds from the OP, you probably won't find the time, to get on track by yourself and the help of your friends/family, easily.
Otherwise get some prof. help that can mentor you on how to get all this sort of thoughts of your chest.
If it's the "panic attack" sort of thing, you are probably going through some stress. Just don't be alone and tinkering in those thoughts all the time and keep in mind that there is no point in overburdening yourself with responsibilities that are not really reasonable and also not helping you.
