Dealing with loneliness in New Zealand

What I did was make a pact with myself to accept any offer from anybody to do anything reasonable.
Someone asked me to go to dance classes. It was so out of my comfort zone but I went anyway. I ended up doing salsa and bachata and kizomba. I also took dance classes in African dance and also swing dance. I know a lot of people who did other type of dancing including ballroom dancing and hip-hop. The dance communities are very inclusive and very friendly and a very good way to meet people and be included. Even if you are extremely shy like I am it becomes quite a support system. It also allows you to get quite a bit of exercise in.
The other thing I did was find a meetup group that did walking and hiking. This was great as it was a way to force me to get into exercise which is critical for not being lonely and feeling good about yourself.
It becomes easy to get into a rut of secluding yourself and staying in your apartment by yourself but you really have to force yourself out to do things. Look up eventfinda and always see what's going on all the time and try to go to as many things as possible. Sometimes you will be all alone but you will never know when you will meet someone interesting.
I found that going out to restaurants and bars alone as a single older guy is not conducive to helping loneliness. You must train yourself to be able to go out by yourself if you do not have anyone to go out with rather than stay at home. It's a good skill to have. Local comedy clubs at night and the theater also offer a respite in the evenings.
Again, make a pact with yourself never to turn down any offer and let people know that you have made that pack with yourself and they were more likely to invite you to things. Also you may want to look in the stores and wine shops for really good deals on wine as you may start to be invited to people's places and you need to come with a gift in your hand. Looking for wine at the last minute can be quite expensive.
