lol i don't know if I'm the right person to ask about running in general...lol but I can just tell you what I did to get into it...I started out slowly because I had pretty poor athsma as a kid- (but thats all gone since I got into running) and i used to run early - when it was still dark, because I was embarrassed! But yeh, I would force myself to run until I felt like I'd collapse, but I didn't start out running the whole way.I used to alternate between walking and running. Eventually I built up enough strength to complete my run without stopping - and I've never let myself stop on a run since then.After that I just continued to increase the distance I was running. The longest I've run for is only 1 hour and 30 minutes, but most mornings before uni I only run for about 30-40 minutes, and I try to run in intervals- running at a normal pace/sprinting for 1 minute and so on...after my run I just try and do about 20-25 minutes of weight/swiss-ball/core exercises each day. If I have a day off from running, I usually force myself to at least go for a 1-2 hour walk with my sister. AND side benefit of running? I reckon it gives you a flat as stomach! Thats about all I can tell you - I hope that helps! I'm sure you can do it! You seem like a hard worker (from what I've read). I hope everythings alright tomorrow- I'm here if u want someone to vent to! take care xx

hang in there girl, things will get better, and i hope you get your period!
stay strong <33
