Hey man, that’s tough. First off, remember (and I’m sure you already know this) that no matter what, you are a valued and gifted individual who is incredibly unique and wonderful. Even if other people don’t hold that confidence, try to maintain it yourself. I’d advise you to focus on the positive experiences that you’ve had with your father in the past. Remember all the reasons you know that your father loves you. If you feel up to it, maybe you could try talking to him (if you haven’t already), perhaps tell him how you’ve been feeling. I’ve always found it incredible how much can be solved and begin to be healed just by talking.
Anyways, that’s just my advice, hope it makes sense. If you want to talk more about it, don’t hesitate to shoot me a PM!
