You consider yourself a “complete loner” but have three close friends. That would suggest you’re not a complete loner. Someone who is a “complete loner” doesn’t interact with anyone. They don’t have friends or acquaintances.
You also stated that you “get told” things about yourself such as you’re not emotional enough or that you hold “little sentiment,” and so forth. I’m wondering who’s telling you these things. The source is important. It could have helped me to determine the validity of the source. Friends can be biased whereas someone like a school official or a therapist would be more objective.
You also stated that you have an interest in true crime. That in itself is not necessarily a problem. However, in the context of increasing social isolation and difficulty interacting with people, it may be a sign that something is wrong.
Generally speaking, when you are concerned about your mental health, you should be evaluated by a professional to determine if something is wrong. Counseling is the ideal remedy for developing the requisite social skills for healthy relationships. Please take care.
