Becoming too dependent on other people for your happiness

Recently I have come to the conclusion that I am far too dependant on other people when it comes to my happiness. I genuinely hate being on my own, which is something I didn't think I would ever feel.

I spent a whole week with Andy recently, him staying at mine, us commuting home from work together, talking for more than five minutes a day (which is our usual phone conversation, consisting of '"how was your day at work?", "fine, yours?", "yeah was ok, you going gym tonight?", "yeah, you?", "yup, do you have any news?", "no not today", "ok have a nice evening" -  basically because neither of us like to talk on the phone), and actually getting to eat dinner together. It was so nice, but the week after he left I was so lost. I found myself feeling pretty shit, even though I am so used to not living with him and only seeing him at weekends. The week he was here I suppose I had something to look forward to after work, and it made the days quicker, I was overall much happier *cringe*.

I suppose the days of feeling shit made me realise that I need to stop depending on other people for my own happiness - I am more than capable of being happy on my own, and deep down I genuinely do enjoy spending time with myself. We should all be happy in our own company, and yes - we should look forward to spending time with loved ones, but our happiness shouldn't rely on that. It definitely has something to do with a fear of being lonely - really I am never truly alone, I live with my family and am always on my phone texting.

I’m sure I cannot be the only person who feels like this, so please do let me know if you have ever felt like this! I’m definitely going to work on not relying so much on other people to be happy myself, and make plans for after work that don’t necessarily involve me seeing friends - things I can do on my own. Are there any things you guys recommend doing on your own? - I'd love ideas!
