I'm having some serious trouble.

I have no controls over my thoughts, I have very unexpected, weird and bad thoughts. I am very emotionally sensitive. I cannot get over things easily .I have mood swings, I feel sleepy and tired all the time.I get distracted and have a feeling that anyone is watching me sometimes .I feel numbness in my brain ,I cannot stay in one mindset for a long time,I get bored easily.I get irritated and angry with little things.I don't have a proper person to talk to. I don't like doing my distractive works even at the time.I cannot talk to anyperson with normal expressions, I get nervous talking even to my family,I have 0 confidence. And moreover I imagine a person to talk to things, I think of enjoying peace with him .I feel like he's talking to me ,he cares and likes me a lot .He's not real ,I can't even get away with my different imagines for even 1 day .I can't study properly even if I'm getting it and little bit liking it.There are much more things that I can't explain properly.
