Does anybody feel the same as me?

I am a maladaptive daydreamer, I figured that I am ever since I read an article of what it was about. Whenever I watch new anime or read manga that I find interesting I always fantasize about the main characters together. After that, since I admire the characters, I start fantasizing about how I have the looks, attitude and personality of one of them. Like I'm creating a fictional me in my head. Even If I finished watching it, it's still fresh in my mind for how many months. This doesn't happen when watching real people movies.  I don't desire the lives of real peole no matter how successful or happy they are. I only desire these fictional characters. I get so into it and can vividly imagine the scenario. I also feel the emotions depending on the daydream. I become happy and act like it's real in my mind. I smile, laugh or cry depending on the situation in my mind, if someone was watching I would look like a fool. I don't think I have a problem in my real life, I don't hate everything except my job. I hate my job, but even though I hate it I don't think I'll ever change if I quit my job. I have a lover, a wonderful and supportive lover. We've been together for four years but I don't feel the same as when we first met or when we were on our first 2 years. When we started going out I only daydream sometimes since my attention is focused. Even with my ex, I once again started daydreaming after the first 2 years.. We broke up, in our 3rd year together since she found someone new. At that time, I have thoughts of killing myself. I feel useless. I don't think I'll have suicidal thoughts ever again, I am a lot stronger now. I will never have suicidal thoughts again but I think the afterlife without pain must be wonderful, that's why I keep enduring and living. I have anger issues, when I'm angry I tend to say horrible words and forgot everything else no matter who that person is, I verbally abuse my lover, but only when I'm angry. I think I am financially stable, I graduated college and passed a board exam. I have a well paying job but I hate it, it's corrupt. I have 4 wonderful cats but I rarely spend time with them, I feel guilty but I'm not doing anything. I keep daydreaming because it makes me happy. I feel empty if I'm not. I feel that I won't be happy if I'm not like the character in my head. Whenever I'm not doing anything I start to daydream like crazy, like a lot of hours, like 5 hours straight. So, am I depressed? Do I have a mental illness? By the way, when my mother was around 45-50s she started hearing voices of our neighbors or relatives, but she's sane. She knows what she's doing, but she's verbally responding to what she hears. Does mental illness run in our blood? I got INTP-A in a personality test, does it have anything to do with it? How can I be happy? I don't want to keep living feeling empty.
