Stressed all the time. Before anything.

I get these intense emotional episodes during the day (which Im able to bear with only if I meditate) where I have a headache, cervical and brain fog. I stress overly about irrational fears and have a negative opinion on my future in general. I'm constantly scared that something bad might happen or I won't get out this pattern I've been stuck in. Sometimes I feel everything is crushing me down while my life is pretty normal. Though, everyday I set up goals for myself which I don't achieve and feel dejected at the end of the day. I look at people for emotional dependence and get hurt over small things, taking things personally. I haven't been in a relationship ever and if I talk to someone (I am) I'll overthink it and obsses making myself weird. I don't say what I want to because I fear people might not like me or may leave me. I panicked before sending an assignment for an interview, so much that my mind almost convinced me that I didn't want to do it. I always do this before anything.
