I am a teenage worrier, here are my problems, how can I solve my problems?

Im 16. I was an anxiety sufferer for 6 months, im cured of that now but im thinking very deeply this last few months. Im constantly thinking about consciousness and the meaning of life, i keep sinking into solipsist thinking, its not that im a solipsist its that i don't want to be a solipsist because you cant live like that. its become a habit. I cant enjoy life without knowing that other people are conscious like myself. I have written down things that reure me like philosophical theories things like the one consciousness theory, subjective reality and holographic universe theories and others which make me feel more positive. I don't like wasting my time worrying about these things. Ive noticed all this worrying has affected my health. Before my first anxiety episode I was very active, happy, sociable, everything was going was going for me. I think I was too egotistic and bad tempered and I eventually realized that my anxiety and depression showed this to me. My first anxiety episode was triggered by excessive worrying over a useless thing. Since then its been ups and downs, highs and lows but I still have that negative voice. Ive lost weight, I look and feel tired all the time. I also cant make proper eye contact with people sometimes, and because i keep thinking about the eye contact I lose track of what people are saying in conversations. I feel like ive lost my personality and sometimes I fear that im going to lose my mind. What can I do to improve my situation or better?
