It’s understandable that you are looking for reasons for your unhappiness but you’re looking in all the wrong places. Your adoptive mom works to support you both. You have as “normal” a family as anyone else does. Very, very few families look and act like the families you see on reruns of old 1950s and ’60s sitcoms (you know: Mom in dress and pearls, Dad in suit, two to three kids all happy, happy, happy). Your father probably is more complicated than you give him credit for. All men are not alike. But you’re a smart girl. You know all that.
So let’s get to your question: Why are you are confused, alone, and unhappy? Partly it’s because you are going through the normal adjustment of adolescence. I know. That’s not a very satisfactory answer. But the truth is that your body is changing and most kids go through emotional turmoil while that is happening – at least for a little while. You don’t have much control over that piece – although you could talk to your doctor to make sure everything is going normally. Sometimes a thyroid imbalance, for example, makes things worse.
The other piece, you do have control over. You are alone and lonely because you’re not with people. However shy you may be, the “cure” is to get involved in something that you really care about with other people. Do you love animals? Maybe there’s an animal rescue group near you. Are you interested in music? Join a chorus or start a band. Do you love working with kids? Think about getting involved with an after-school program or some other activity where you could work with little ones. Are you interested in kids with special needs? I bet there’s an organization near you that works with them. By giving of yourself and by working side by side with others, you’ll start to find people who are more like you and meaning for your life.
Meanwhile, you also have some control over your relationship with your mother. Find two or three positive things to say to her every day — regardless of whether you think she deserves it. By going to work every day, she is providing for you. She adopted you because she really, really wanted you. She didn’t have to do it. She’s probably as confused and upset about your relationship as you are. You are both dealing with the teen years for the very first time. You’re both learning. Most parents have just as difficult of a time with it as their kids do, though in different ways. If you take the initiative and work to change the tone in your house a bit, you may be surprised and pleased with what happens.
I wish you well.
