Is it normal i want to be alone most of the time?

I wouldn say that normal because i have the same problem. It started just like that where i just didnt feel like hanging out with anyone and i would make excuses. But it lasted a very long time, i just lost interest in my friends. Its not to say i didnt want friends, but i just felt like being alone and expected them to still stick around and see each other later on down the road like nothing happen. Didnt work out that way. It cost me a very close friend too. Later on i found that it really diminished my quality of life because by having lost almost all my friends, (ever since that time the only best friend ive been able to maintain is my boyfriend) i felt almost like i didnt belong to the world anymore. Like nothing really mattered and the people i was surrounded by seemed so foreign to me somehow. I was pretty much scared to go out at all eventually because i felt like i was entering some foreign world. It made a lot of problems very stressful because i had very few people i could confide in, and if i had a problem in a relationship i just didnt have anyone to go to for advice. By the time i got to university, i was just utterly terrified of meeting new people and didnt have the courage to do a lot of things i wanted to do because i didnt have anyone to go with me that i knew. It was really a low time for me. I felt very isolated from te world and consequently i was pretty depressed too. Didnt even want to get out of bed in the morning...

Basically everything became a mess and thats what that led to. I just lost all my motivation. Its fine if this feeling of yours goes away, but if it doesnt i really suggest you see a therapist even like at your school or something, because it leads to much bigger problems. Try to think about why you lost interest in hanging out with them. Is it something temporary or something that can be changed? Make sure you dont lose people you care about over this kind of problem, or maybe if it gets bad you can tell them about it and hope they are willing to be supportive. I find that after what happen i had a LOT of trouble making friends. It was so bad. Best of luck to you!

Yes, it's normal. I sometimes don't leave my house for a whole day. I love my friends, and hanging out with them, but sometimes I just don't wanna see anybody.

I get like this sometimes as well. I have fun hanging out with my friends but it's great to just relax and enjoy your own company once in a while.
