Okay so before I begin you might want to know I'm a 16 year old female.

I feel emotions but I have a hard time getting excited about things. A lot of people tell me that I'm often expressionless and have a flat voice. For example, if someone told me that they bought me tickets to see a concert of a band I enjoyed, I might feel inwardly happy, but it feels very unnatural and forced to do anything but flatly be like "oh... thanks" I'm not sad about anything I just have a hard time being outwardly happy or excited.

Maybe it's because I'm a very shy person and in social situations I don't know what to say unless it's someone I know well and I know they wouldn't find me or my mannerisms weird. If I do go out with people I get very tired and just want to go home and sleep.

I'm very lazy on the weekends and prefer to lounge around and do nothing, and during the week I want to do the same so I procrastinate on my homework and end up getting only 5 or 6 hours of sleep because of it. I am involved in a few extra curricular activities, and enjoy them to a degree, but I always feel bad afterwards because I feel like I can't properly socialize with people.

I don't care of myself either. I do basic things like take a shower every day and brush my teeth but I don't make my hair look very nice, I don't wear makeup, I go long periods of time without shaving, I wear the same couple clothes that are often baggy and plain, I'm like 20 pounds overweight and don't exercise or eat very healthily, and when I try to correct any of these things I end up reverting back to my old habits within a couple weeks. I feel unattractive because of all this and it makes me want to hang out with people besides my couple of close friends a lot less.

Also it's probably worth noting that I find other people attractive and like the thought of relationships/sex, but I don't have much of a sex drive and have never felt any urge to masturbate.

Yeah so like I said, despite this, I've never been unhappy or sad, I just feel like I have no energy which means I can't find the energy to try and hang out with other people and be more involved and try to outwardly display emotions.

If anyone has any thoughts on this, I'd be happy to hear them, thanks.
